I've heard that the UTC reg hack for Windows has some downsides and
that Windows does not always honor the registry value, though I am
starting to consider this.

Unfortunatley the gnome applet shows that I have "System Clock uses
UTC" set and I am unable to clear it due to the missing rtc dev file.
Interestingly enough when I run timeconfig it shows that "System Uses
UTC" is not checked.  My TZ is correctly set.

Interesting that you bring it up as I am booting with apcpi=off to
avoid a system hang.  I wonder if I'm seeing some nasty results of
acpi issues.  My particular hardware is as follows (not that it will
help much):

CPU + MEM:

  Intel Core 2 Duo E6600
  2GB RAM

MOBO:

  MSI 975X platinum v2
  Intel 975X northbridge
  Intel ICH7DH southbridge
  JMicron JMB361 --- DISABLED IN BIOS

VGA:
  Nvidia 8800 GTS

It is an x86_64 install of Fedora 9.

I'll look into this further see if anything comes of it, thanks for the help.
