I get the same panic with the June i386 snapshot on my Dell Inspirpon 
1501 (which has a dual core AMD Turion TL52 CPU).
It doesn't have a serial port or firewire, so I can't capture a complete 
log of the boot and crash.  However, I've copied the last boot messages 
and the backtrace below.   I also tried booting with ACPI disabled, but 
the system paniced much earlier during the boot process with a GPF.
