Well, my CPU is a "Intel(R) Core(TM)2 Duo CPU T5750 @ 2.00GHz", which
doesnt even have Intel VT, so i guess i dont have an IOMMU.

My .config for the test kernel says the following:

brotscheibe linux-2.6 # grep IOMM .config
CONFIG_GART_IOMMU=y
# CONFIG_CALGARY_IOMMU is not set
# CONFIG_AMD_IOMMU is not set
CONFIG_IOMMU_HELPER=y
CONFIG_IOMMU_API=y
# CONFIG_IOMMU_DEBUG is not set
# CONFIG_IOMMU_STRESS is not set


I hope that helps,
Michael
