[2.5.63 and prior] Voodoo3 framebuffer bug

Kernel is compiled with gcc version 2.95.4 20010319 (prerelease)
That bug was in previous versions too.
I've got Voodoo3:
01:00.0 VGA compatible controller: 3Dfx Interactive, Inc. Voodoo 3 (rev
01) (prog-if 00 [VGA])
         Subsystem: 3Dfx Interactive, Inc. Voodoo3 AGP
         Flags: 66Mhz, fast devsel, IRQ 11
         Memory at e4000000 (32-bit, non-prefetchable) [size=32M]
         Memory at e8000000 (32-bit, prefetchable) [size=32M]
         I/O ports at c000 [size=256]
         Expansion ROM at <unassigned> [disabled] [size=64K]
         Capabilities: [54] AGP version 1.0
         Capabilities: [60] Power Management version 1

Framebuffer works really strange.
- when I start it in 1024x768-16@75 I have strange colours: background
is brown-red, other colors are not good too (techno-like style). See
dump from 1024x768 16bit: http://piorun.ds.pg.gda.pl/~blues/dump.bz2
I don't know how to make screenshot on console better, sorry...
- I can't set other refresh rates than 60Hz - from lilo I've passed
append="video=tdfx:1024x768-16@75", but I've became 60Hz set.
- when I set resolution with fbset to i.e. 1280x1024 I have resolution
changed but avaible area is in old size.
- when I set resolution to other than passed from lilo: when I switch
from X, my screen is completely not usable. Manual setting resolution
(without visibility) makes it usable again - until next switch.

P.S.: sorry for my english - I hope you understand what I mean...
