7.2->7.3 xorg hangs (ati/radeon, AGPFastWrite)

[Jan Henrik Sylvester]

Hello!

The 7.2->7.3 update was not as painless as expected... xorg hanged the 
system. After starting with a fresh xorg.conf that did not lead to the 
hang, eventually I found AGPFastWrite to be responsible.

This happens with the ati driver that "X -configure" selected as well as 
  with the radeon driver that is more appropriate. (Reproducible with 
the xorg.conf from "X -configure" with just AGPFastWrite enabled.)

My board is "Radeon RV250 [Mobility FireGL 9000]".

This has probably nothing to do with FreeBSD. Therefore, I should report 
to xorg... but in case anyone runs into the same problem or has a clue 
why this happens, I report it here.

(Also, KDE uses way too big fonts for everything since the upgrade -- 
but this is totally unrelated.)

Regards,
Jan Henrik
