"hmmm" Since this works for me, I'm assuming it must be a problem
specific to the tsunami. I don't suppose either of you has an X log
from your attempt to start the X server? Even starting it remotely
and saving the output of your ssh session would be helpful.
Anyway, do you see it reporting ****INVALID MEM ALLOCATION*** in the
log? If so, I've seen a similar problem on my UP1000 where the X
server was too smart and tried to remap the AGP video card into space
reserved for something else.. Its usually bad news when the X server
tries to change the mapping.
One blind shot in the dark is to change
xc/programs/Xserver/hw/xfree86/os-support/bsd/bsdResource.c's
xf86PciBusAccWindowsFromOS(void) RANGE to allow everything, like
Linux's:
Eg, make it look like this:
resPtr
xf86PciBusAccWindowsFromOS(void)
{
resPtr ret = NULL;
resRange range;
/*
* Only allow the upper half of the pci memory range to be used
* for allocation. The lower half includes magic regions for DMA.
* XXX this is not right for XP1000's and similar where we use the
* region 0x40000000-0xbfffffff for DMA but this only matters if
* the bios screws up the pci region mappings.
*/
RANGE(range, 0x00000000, 0xffffffff, ResExcMemBlock);
ret = xf86AddResToList(ret, &range, -1);
RANGE(range, 0x00000000, 0xffffffff, ResExcIoBlock);
ret = xf86AddResToList(ret, &range, -1);
return ret;
}
Let me know if that helps. I'll be out of town all next week, so if
we can iterate about this over the weekend that would be great.
