Ubuntu 7.04, T43, x300, rovclock

[nmuntz]

Has anyone successfully changed their core and/or memory speeds on an X300 with rovclock in Feisty Fawn? Any value I give it causes X to lock up solid and I have to reboot. I've tried both the rovclock package in universe and compiled from source and both produce the same result.

It was working fine under Dapper.
