Point taken about Fusion being different from Workstation. A running VM reports 
itself as "vmware hardware version 6", for what that's worth.

Kernels since 121 definitely *did* panic when booting in VMware Fusion, and for 
them the kernel stack trace included:

pcplusmp`ioapic_read+0x1f(ff, 20e)
pcplusmp`apic_rebind+0xad(ffffff008fbb0c1c0, 0, 0)
[...]
pcieb`pcieb_intr_init+0x2a0(ffffff008fb471d8, 1)
[...]

Booting 127 with -a and without disabling pcieb prompts me for the system file 
[/etc/kernel], then the retire store [/etc/devices/retire_store], and then 
panics with a similar stack trace to above, ie including pcieb.

Cheers,

Chris
