Well none of that worked.  My BIOS wont let me disable the PS/2 ports.  The 
ums device doesn't show up in the vmstat -i listing, and disabling acpi 
(which also disables HTT for me) doesn't result in any improvement.  Maybe 
there is more hope of fixing the device probe on PS/2 than fixing USB 
performance? At least for right now.
