Only did a quick scan, but the changes look nice so far.  I'll take a closer 
look and give it a try locally tomorrow.

On an unrelated note, can you take a look at the "PCI MSI breaks when booting 
with nosmp" thread?  I posted a patch there that unconditionally enables the 
local apic with nosmp/maxcpus=0 so that MSI will work correctly.  The other 
option of course is to disable MSI when nosmp/maxcpus=0 and local apic enable 
code alone.

Thanks,
Jesse
