FWIW Ubuntu 10.4 has been a total wipeout for me on my older Thinkpads ( I have several ).
Hibernation just goes out crashingf into the woods, requiring a power down to get back.
Wireless won't handle anything over a few seconds long without a disconnect.
This has been this way since the beta and seems to be set in stone.

The last six versions were fine, I/m doing this on 9.10.
10.4 is OK on several desktops.
