No I don't, the default installation (without me changing things) came with 
the radeon driver enabled and direct rendering (checked with glxinfo).

This is the PSA70C-DD100E model 
(http://www.toshiba.ca/web/product.grp?lg=en&section=1&group=223&product=3150&part=2631#spectop)
it has a Celeron D 335 @ 2.8GHz 256KB L2, 512MB RAM - 64MB for Video; as I 
said ATI Mobility Radeon 9000IGP (missdetected by ubuntu as 9100IGP), original 
BIOS.
I had hardy for over a year and it worked almost perfect, I can't see that 
resource needs of jaunty (kde4). Also, as I lately said, a friend of mine have 
the same software configuration on a dell inspiron 1300, that is very similar 
to this one, maybe the main diferences are that he has a pentium CPU and intel 
graphics, and works great. The RAM is not the main reason because I use almost 
no swap, the CPU utilization doesn't goes with the swap utilization, so I 
think is not the RAM.
