The cause for the blue-screen appears to be seabios, which leaves only 0x20
slots for “smp_mtrr”s.
Apparently, the increase in the variable range MTRR count caused it to exhaust
the available slots.
As a result, some MSRs are not initialised by the BIOS (specifically, 3.5-4GB

I reproduced the blue-screen. Let me to to figure it out.

In addition, it just can be reproduced on 32bit win7 w/ MP enabled, in
case UP can't be reproduced.

Recent Intel CPUs have 10 variable range MTRRs. Since operating systems
sometime make assumptions on CPUs while they ignore capability MSRs, it is
better for KVM to be consistent with recent CPUs. Reporting more MTRRs than
actually supported has no functional implications.
