mmm.. i found out the truth.
i write this just for information (probably most of you already know it but it can be useful to post it anyway).
catalyst 9.3 and earlier drivers don't support x 1.6 and catalyst 9.4 doesn't support a bunch of older radeon cards (as mine).
This means the only option one has is to downgrade to ubuntu 8.10.

Thanks Jack,
as IOhannes confirmed it is probably a driver problem (anyway i don't think i can make faster my pacth with [pix_snap] and family since they will eat my cpu.., i prefer to manage this driver issue).
@IOhannes
gfx card:
VGA compatible controller: ATI Technologies Inc M56P [Radeon Mobility X1600]
driver:
xserver-xorg-video-ati 1:6.12.1-0ubuntu2
xserver-xorg-video-radeon 1:6.12.1-0ubuntu2yes, keep on looking i found out the same suggestion in other forums.
i suggest using the latest (urgh) proprietary drivers to get decent openGL performance...
ok, i'll try to install that right away .. (i was afraid to hear it) :P
