allright, thanks to this link http://nl.opensuse.org/Howto/ATI_Driver
, I was able get some graphics support for the onboard video chip, ati radeon x1250. My acer tft screen, al1715, wasn't in the supported list in yast, so it still ran on vesa 800x600, but i discovered it was compatible with the 1555.
Some kind of progress, but booting time is still bad, and i don't understand suse's memory management. Like it just uses all it can get to cache data, while debian seems to use the least possible which I prefer.
