Since 6.03-pre19 and 6.03-pre20 seem to be behaving in the same exact 
way regarding (l)pxelinux.0 (whether successfully or failing) in this 
hardware, I would tend to think that commit:
 1ada8a37ae30c2e4283c3e65444ccd72cf8a2e85 
"PXE ISR: Force polling on select hardware #3 WORKAROUND"

which is included in 6.03-pre20 but not in 6.03-pre19, might not be 
really necessary.

The original problem might have been solved already by commit:
 a7f5892c4d85f3685708b8efb237c9c73a8b1ddf 
"core, pxe: Don't push on one stack and pop from the other in pxenv"

which is included in 6.03-pre19 already.

In other words, the 3rd workaround seems to be now unnecessary. I am 
wondering whether, perhaps, the prior 2 workarounds might be also 
unnecessary now.

Ady.
