cpu0: FMI,MB86907 (mid 0 impl 0x0 ver 0x4 clock 1083 MHz)

WARNING: clock gained 3987 days -- CHECK AND RESET THE DATE!
Guess, which OS is it?
Yes, NetBSD 1.3.3 is bootable after this patch too! Actually all the versions between 1.3.3 and 1.5.3 are bootable, and even with OpenBIOS.
According to the chipset documentation, interrupts are cleared by disabling and then re-enabling them, not by disabling them as it was done in qemu before.
