Ok.

Hmm, the radeons have VERY fast blitters, I'm sure you'd notice the 
difference immediately - if there was the tiniest trace of sluggishness 
regarding graphics operations then you can be fairly sure it was wsfb.

Xorg is /very/ picky about freetype. The freetype2 in xsrc/dist should 
work with the Xserver in xsrc/xorg ( well, I'm still using it on a 
sparcbook ) but probably not with any newer xorg release.

Hmm, all black or different trouble?
If radeonfb shows the same symptoms as xfree's radeon driver that might 
be the same problem. When you try radeonfb again please mail me the 
complete dmesg output, it /should/ complete booting and let you in via 
ssh even if the driver produces no readable output. Currently radeonfb 
spews a load of debug info, some of it might help finding out what's 
going on.

have fun
