hardware-support missing after upgrade to 10.04

Hi,

after upgrading my machine from 9.10 to 10.04
(01:05.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3200 Graphics)
moving windows, scrolling etc. has become extremely slow, obviously hardware support is missing.

I also had trouble removing the fglrx package for testing, since the postrm script tried to undivert
/usr/lib/libGL.so.1.2 which was missing, thus causing dpkg-divert to abort with error and making
the package unremovable (without manual interaction).

I guess both problems have the same reason, a missing link or lib file, which causes the X server to not have GL support and the removal script to fail.

regards
