As for you belief that the the mujahideen were NOT Islamic fundies, well, Brzezinski explains that they were useful surrogates just because they were religious zealots and thus useful in toppling a secular state.
From
http://en.wikipedia.org/wiki/Zbigniew_Brzezinski#Afghanistan :
Brzezinski, known for his hardline policies on the Soviet Union, initiated a campaign supporting mujaheddin in Pakistan and Afghanistan, which were run by Pakistani security services with financial support from the CIA and Britain's MI6. This policy had the explicit aim of promoting radical Islamist and anti-Communist forces to overthrow the secular communist People's Democratic Party of Afghanistan government in Afghanistan, which had been destabilized by coup attempts against Hafizullah Amin, the power struggle within the Soviet-supported parcham faction of the PDPA and a subsequent Soviet military intervention.
June 13, 1997, in a CNN/National Security Archive interview, Brzezinski detailed the strategy taken by the Carter administration against the Soviets:
We immediately launched a twofold process when we heard that the Soviets had entered Afghanistan. The first involved direct reactions and sanctions focused on the Soviet Union, and both the State Department and the National Security Council prepared long lists of sanctions to be adopted, of steps to be taken to increase the international costs to the Soviet Union of their actions. And the second course of action led to my going to Pakistan a month or so after the Soviet invasion of Afghanistan, for the purpose of coordinating with the Pakistanis a joint response, the purpose of which would be to make the Soviets bleed for as much and as long as is possible; and we engaged in that effort in a collaborative sense with the Saudis, the Egyptians, the British, the Chinese, and we started providing weapons to the Mujaheddin, from various sources again—for example, some Soviet arms from the Egyptians and the Chinese. We even got Soviet arms from the Czechoslovak communist government, since it was obviously susceptible to material incentives; and at some point we started buying arms for the Mujaheddin from the Soviet army in Afghanistan, because that army was increasingly corrupt.

Milt Bearden wrote in The Main Enemy that Brzezinski, in 1980, secured an agreement from the Saudi king to match American contributions to the Afghan effort dollar for dollar and that Bill Casey would keep that agreement going through the Reagan administration.<14>
January 18, 1998, Brzezinski was interviewed by the French newspaper Nouvel Observateur on the topic of Afghanistan. He revealed that CIA support for the mujaheddin had started before the Soviet invasion and was indeed designed to prompt a Soviet invasion, leading them into a bloody conflict on a par with America's experience in Vietnam. This was referred to as the "Afghan Trap." Brzezinski viewed the end of the Soviet empire as worth the cost of strengthening militant Islamic groups. Full Text of Interview
In his 1997 book The Grand Chessboard, Brzezinski says that assistance to the Afghan resistance was a tactic designed to bog down the Soviet army while the United States built up a deterrent military force in the Persian Gulf to prevent Soviet political or military penetration farther south (see: the Carter Doctrine).
