Another one: parse error reading X server string `intelfb'

["H.A.J. Koster" <H.A.J.Koster@uva.nl>]

Hi,

I've just downloaded a lot of stuff from Debian testing (using also the 
debian-installer) onto my new Dell Dimension 4600 computer. Everything 
went fine, except X won't start. XFree86.0.log says at the end:
(EE) No devices detected.
Fatal server error:
no screens found

dpkg-reconfigure xserver-xfree86 says (twice):
parse error reading X server string `intelfb'

Main board has (integrated) Intel 82865G Graphics Controller. Debconf 
probed this and assigned driver "apm" in XFConfig-4; I've also tried 
"i810", same (EE) message. Removed, then reinstalled xserver-xfree86 
from scratch, no change.

I'm stumped, any ideas?

Regards,
