No ... the machine immediately reboots to the bios loading screen ...
fsck is required on startup ... and /etc/X11/xorg.conf and /var/log/Xorg.0.log get wiped out ... and nothing relavent appears in dmesg or /var/log/messages. Really crummy in terms of getting any useful error messages ... :/

Yes it is ...
Also .. some more information ... I've tested this on Linux (Fedora14) as well and get a similar result .. it doesn't reboot ... but the system immediately becomes unusable ... freezes (*literally completely unresponsive*) ... kernel is 18.104.22.168-63_x86_64 if anyone is concerned.
In windows (*of course*) ... everything appears to work just fine ... :/ ... if you're into that sorta thing.
Also, the laptop has an integrated video (Sandy Beach PoS intel card) ... currently I have this running Fedora since the updated linux kernels support KMS/GEM ... while FreeBSD does not :/ .... *sigh*.
Hope this additional information may bring resolution.
Thanks again for your responses and suggestions.
