CVS change which seems to introduce the problem

Seems that the problem was introduced by this CVS commit:

date: 2005-04-26 05:19:11 +0000;  author: anholt
Convert BSD code to mostly use bus_dma, the dma abstraction for dealing with
IOMMUs and such.  There is one usage of the forbidden vtophys() left in
drm_scatter.c which will be fixed up soon.  This required a KPI change for
drm_pci_alloc/free() to return/use a drm_dma_handle_t that keeps track of
os-specific bits, rather than just passing around the vaddr/busaddr/size.

Submitted by:   Tonnerre Lombard (partially)
Tested on:      FreeBSD: Rage128 AGP/PCI
                Linux:  Savage4 AGP/PCI
