Linux guests crash with Call Trace - Intel DQ67SW mainboard

I just experienced Call Traces nearly every time I wanted to boot (different) Linux(es) as guest on my Windows 7 Pro SP1 x86_64 host.
My hardware: Intel DQ67SWB3 mainboard (BIOS revision 53), Intel Core i7 2600 (non-K, non-S) CPU.
Sporadically, I could boot into the guests, but mostly they crashed, no matter wether these were 32 or 64 bit guests. Disabling I/O-APIC in the VM configuration, nor "noapic", "nolapic" etc. in the guest worked... The only solution that worked for me was: either to allocate more than 1 CPU to the guest or to disable VT-x support (which only works for 32 bit VMs).
Ubuntu 10.04 (server) x86_64 as host seemd to work fine, but I don't know if that was just a coincidence or maybe Linux is more "fault-tolerant(...)".
The "real" solution for this problem was different and simple: Updating the BIOS revision to 54 that Intel just released a few days ago ( http://downloadmirror.intel.com/20333/eng/SW_0054_ReleaseNotes.pdf -> MWAIT fix). Since I upgraded my BIOS, no Call Traces occured anymore...
I also attached the logs where you can see the inconsistency of the MONITOR/MWAIT flag.
Thanks a lot for the help and support of the friendly guys on IRC (especially MichalM).
