[gentoo-amd64] hardware clock often doesn't sync to system on shutdown

[Thanasis]

I have a laptop (Gateway T-1625), set up with ntpd to sync the system 
time (with the "-s" option in /etc/conf.d/ntpd) to a local system of the 
LAN.
What happens is tha although it syncs the system time successfully, it 
often fails to sync the hardware clock during shutdown although I have 
set CLOCK_SYSTOHC="yes" in /etc/conf.d/clock, and so I see those "One of 
the files in /etc/{conf.d,init.d} or /etc/rc.conf has a modification 
time in the future!" boot messages. Then I can confirm the difference in 
time using the commands "date" and "hwclock --show" which shows the 
difference, eg:

# hwclock --show && date
Thu 11 Sep 2008 09:55:22 PM EEST  -0.228853 seconds
Fri Sep 12 08:58:30 EEST 2008

Here is some more info in case you need it:
# rc-update show |grep clock
               clock | boot 
# uname -a
Linux dwarfy 2.6.24-29Aug-r8 #1 SMP Fri Aug 29 06:56:28 EEST 2008 x86_64 
AMD Turion(tm) 64 X2 Mobile Technology TL-60 AuthenticAMD GNU/Linux

I suspect buggy hardware and bios. Maybe related to another problem, the 
system's clock freezing for random intervals if I don't boot the system 
passing "noapic" or "noirqbalance" to the kernel .
