 For direct rendering with MGA graphics cards use the following option in
 the Device section of xorg.conf:
 Option OldDmaInit true

Someone should fix the mga X driver to fall back to the old DMA init
method if the new one fails.

Why not making a patch of the kernel module for kernels 2.6.14 and 2.6.15?
The problem has obviously been solved in November last year, see

Can you please add the workaround described below to the DRM problems
with kernels 2.6.14+15 to next release of Xorg. Obviously the kernel
module patch will not be included until kernel 2.6.16.

  Recent kernels 2.6.14-2-686-smp and 2.6.15-rc4-686-smp does not have 
  direct rendering enabled. Kernel 2.6.11-1-686-smp works OK.
  
  Kernel 2.6.14:

 It seems that this bug has been solved in the DRM module in CVS in
 November, see https://bugs.freedesktop.org/show_bug.cgi?id=4797
 
 The problem is that the changes are not included in kernels 2.6.14 and
 2.6.15 (released yesterday). I've asked on the DRI-devel mailinglist if
 a patch can be made available that can be included when building these
 kernels. If not, a workaround is to add the  Option OldDmaInit true
 in the Device section of xorg.conf for the card as a workaround. My
 problems were solved by this setting for the card, an MGA G400 DH AGP.
