I don't have any hardware for this driver, and never really contributed
anything to its development, except for a few patches that are quite
obvious.

I'll CC the linux-fbdev list as well as Alex Kern.

In the meantime, can you try the ff:

1. enable/disable CONFIG_FB_ATY_XL_INIT in your kernel
config and see if that makes a difference.

2. Try using fbset to adjust the display settings, or pick a new
mode.  Remember to set csync to high.

3.  Does xfree86 manifest the same problem if atyfb is off?

4.  Can you post the dmesg, config and fbset -i of both the
working and non-working kernel?
