panic: npxintr from nowhere

Description
Hi,
I'm trying to install DragonFly BSD onto a small geode based board
(http://www.pcengines.ch/alix2c3.htm if this can be of any use).
I'm booting up a laptop with the live CD, running the "Setup NetBoot
Install Services" to boot from PXE. Just to ensure this wasn't in a
given version I tried with:
- 2.2.1
- 2.4.1
- LATEST downloaded on 23th of november
Attached is the full dmesg, here are a few hilights:
npx0: <math processor> on motherboard
npx0: error reporting broken; using 387 emulator
npxintr: npxthread = 0, curthread = 0xc168c6f0, npx_exists = 0
panic: npxintr from nowhere
Trace beginning at frame 0xccc4ccf4

I've ported DragonFly to a Geode LX (Soekris net5501) a few months ago. I'll
take a look at this issue whenever I have some time (hopefully later this
week).
Cheers,
Alex Hornung

polachok provided a patch (attached) and generated a new iso for me to test.
It seems to have resolved the issue.

Is it safe to assume that every SMP CPU has FPU set in cpuid? Then we could
remove code duplication.
See the patch:
