Odd.  you might also try adding the agpgart module with the
"try_unsupported=1" option, although if it worked before without the
option...  Another thing you might try is building sis framebuffer
support as a module or into the kernel.  I know you don't have a sis
video chip, but the two were kind of intermixed for a while when sis
originally wrote DRI support for their 300 series cards.  probably a
long shot though.
