The IBM website states that the R51 has an old ATI Mobility RADEON
7500, which is based on the rv200 chip. The XFree86 drivers provide
hardware DRI support up to the Radeon 9200. The real trick is to get
accelerated 3D on a Radeon >= 9500, which are based on an r300 chip or
higher. This is what the r300 driver is for.

For a short summary, you can look at
