I got one of these a month ago, but it's having some ACPI issues. I've
modified the ASL to get rid of warnings as per the ACPI handbook, but
the interpreter complains about missing methods and no handler for the
RTC CMOS region. Some of the methods that generate an AE_NOT_EXIST are
actually there, but in the error message it looks like the method name
is mangled (usually prefixed by an integer).
Here's a list of the problems, with snippets of the system logs with
ACPI errors. The original and modified ASL are at
http://www.qtchat.org/laptop-dsdt.asl.orig and
http://www.qtchat.org/laptop-dsdt.asl
respectively; posted log snippets are from running the modified ASL.
1. When powering off via the OS (either via '/sbin/shutdown -p now' or
via the KDE4 UI) the unit does not power off (go to S5); "Press any key
to reboot" is displayed. Here's a hand-transcription of the logs:
usbus3: Controller shutdown complete
usbus4: Controller shutdown

2. Suspend (S3) using zzz(8) or closing the laptop lid with
hw.acpi.lid_switch_state=S3 and debug.acpi.resume_beep=1 results in
(usually) 1 beep and the machine returning to the state before the
suspend action was initiated. Here's /var/log/messages snapshot of the
resume:

3. Brightness controls do not adjust brightness. I got an ACPI error
about method _BQC missing whenever I pressed the brightness up/down
keys. I added a method which returns 0x1E, which is a value from the
_BCL method which returns all supported brightness levels:
Method (_BQC, 0, NotSerialized)
{
Return (0x1E)
}
but no change (except I get no ACPI errors when pressing those keys).
4. Here's a grep for AE_NOT_EXIST showing the missing methods. I *have*
_PTS and ESDT methods, but the interpreter complains about not finding
method "\134_PTS" or "\134_SB_.WMID.ESDT".

Unfortunately I'm due to ship my laptop for warranty service (unrelated
mechanical issue) like tomorrow. I can hold off shipping it for a while
if we can tackle these issues though.
Linux recently added an RTC CMOS ACPI driver; I'm probably gonna try my
hand at a FreeBSD analog.
