Thanks.  Please send me the debug output.  There's no real intelligence 
in the
driver when deciding whether to use MSI or the fixed interrupts.  If the 
card
and the bus drivers say they are all MSI capable (re: 
ddi_intr_get_supported_types()
returns DDI_INTR_TYPE_MSI) the driver trusts this and enables MSI delivery.
I know one person who has a GeForce 6150 based motherboard where MSIs work,
so it must be a subtle failure.  Maybe some common feature will show up
in all the failing systems where the driver can automatically disable
MSI use.
