floppy reads hang in qemu

[GoogleCodeExporter]

when trying to read floppy (no floppy configured in qemu) the
process hangs arround and qemu cpu goes up.

this problem appeared when i removed nvram= and nvram partition
from a qemu image. libauthsrv's findnvram() will try the floppy
drives to read the nvram and that will hang there forever.

trying to acid -k the haning process doesnt give mutch info
as we released the cpu and wait for dma or whatever to finish.
(someone write kstk function that can traverse interrupt contexts)
