I have another related idea. I just got a Compaq 6000 working, and the
problem seemed to be due to the SCSI and TLAN Ethernet controllers being
both on IRQ 11. The TLAN was an unknown device (the driver is not yet
written either) and if the kernel saw an interrupt from it it would likely
cause major confusion in the SCSI (aic7xxx) driver. So see if you can
ensure that nothing is sharing IRQs and see if that helps.

The symptom I saw was rebooting near the end of kernel initialization,
around the time the floppy driver was about to be started. Did your system
hang or reboot?

As for MMX, I believe it highly unlikely it is implicated here, probably
there is something else different in your laptop besides MMX, like a
different version of some PCI device from the non-MMX laptop.
