Re: patch-2.4.19-pre5-ac2

[Jonathan A. Davis]

The radeon updates in pre5-ac2 seem to make a minor mess out of my Radeon
7500's console fb.  After X starts up -- switching back to a text console
results in artifacts from the X display contents plus borked scrolling.  
No tendency to crash though and switching back to X results in a normal X
display.  I dropped out the patches to:

drivers/char/drm/radeon_state.c
drivers/video/radeon.h
drivers/video/radeonfb.c

Which returned things to normal.  I'm not up enough on the kernel fb stuff 
to dig into the patch guts very effectively.

The mb chipset is a VIA K266A with very conservative (no overclock, 
etc...) settings.  Processor is an Athlon XP 1700+.

Here is some boot/config info:
