It looks like 2.6.12 is able to relocate the BAR regions for the GPUs (see dump below).. peter -- PCI: Cannot allocate resource region 0 of device 0000:81:00.0 PCI: Cannot allocate resource region 1 of device 0000:81:00.0 PCI: Cannot allocate resource region 2 of device 0000:81:00.0 PCI: Cannot allocate resource region 0 of device 0000:41:00.0 PCI: Cannot allocate resource region 1 of device 0000:41:00.0 PCI: Cannot allocate resource region 2 of device 0000:41:00.0 PCI-DMA: Disabling AGP.
