A couple of things to note: DOS UNDI drivers expect the netif to be 
closed when they start, it seems.  The change was removing the 
shutdown() call from bzimage (for undionly.kkpxe).  While 'startpxe' 
helps the exact same test for normal gPXE drivers, it seems that it 
actually hinders undionly.kkpxe with the shutdown() call removed.  
Debugging revealed that netdev->ops is overwritten during netdev_open() 
for the UNDI netif, though its ->name was intact.

somedriver.gpxe with 'startpxe' -> MEMDISK -> DOS UNDI -> Ok
undionly.kkpxe with 'startpxe' & (shutdown() removed) -> MEMDISK -> DOS 
UNDI -> Failure
undionly.kkpxe with 'ifclose' & (shutdown() removed) -> MEMDISK -> DOS 
UNDI -> Ok

'startpxe' was thus only a regression only so far as my testing 
processes go for undionly.kkpxe, which I hadn't tested for a long time. :)
