Hi people,
I can't use frame buffer (tdfxfb) in linux-2.6 with 1GiB of RAM, but yes with 512MiB.
(The linux-2.4 works ok, in both cases.)
HIGHMEM disabled.
The another problem is, when boot in low resolution default 640x480 and switch with
fbset to 1024x768 for example, it changes ok, but can't draw in all screen, only in a
small area of 640x480 located at upper left of screen, the same for all VTs.
If you need more info in logs/proc/sysfs please let me know.
the @dmesg (1GiB) appears:
fb: Can't remap 3Dfx Voodoo5 register area.
tdfxfb: probe of 0000:01:00.0 failed with error -6
and @dmesg (512MiB):

Working on a fix. Basically we need to migrate as many drivers as possible
to use acceleration and remove the ioremapping code. To do this tho I have
to replace the fb_read and fb_write functions with someothing that uses
the accel engines. I haven't finished that code yet.

Fixed in the fbdev tree. That will be synced up soon.
