My XF86Config-4 file
BTW, I am running XFree86-4.1.0-0.8.6.
I do see a bit of a slowdown with VC switching on the Radeon driver.
Perhaps something performance enhancing is disabled by default now..
Not sure, but I'll look into it.
The VT switching code for Radeon has an intentional delay placed in it
to solve some type of race condition. It isn't 2 seconds long, but
perhaps there is other reasons it is delayed also. At any rate, while
a bit annoying to some, it is not a mission critical bug IMHO worthy
of spending any significant amount of time on, since there is no
crashing or display corruption. It is likely to get fixed upstream
at some point when it anoys someone enough.
