Yes, I can recommend Erik' s 9atom, too, it solved my problems with installation onto a SATA-II HD some time ago...

it does support ahci controllers.  vbox causes problems for a lot of oses,
and that's probablly a bigger project.

i'm going to guess this is a power management issue.  the ahci driver
was written before the standard, and thus has been a little slow in
catching up.

could you try downloading 9atom, which is quite close to the distribution
(http://ftp.quanstro.net/other/9atom.iso.bz2)?  it has a few power
management wiggles that may fix your issue.
