Let's not finish this just yet! I'd like to try and nail down exactly
what's going on so PRs can be filed.

* Is this with 9.2-RC2? Are you wiling to try out a -HEAD snapshot to make
sure this stuff in -10 is also going to work?
* Ok, so if you have no VESA option, does suspend/resume work in console
mode?
* Try manually setting the cpu frequency low and high (sysctl dev.0.cpu -
you can change 'freq') - see if that fixes your speed issues. Someone else
has reported this.

Thanks!
