Forget everything so far, and grab the latest commit that I just pushed: http://git.ipxe.org/ipxe.git/commitdiff/cc9f31e. There was a regression causing the flags as returned by int13() to be overwritten during the return from VIRT_CALL(). The net effect was that OF would never be set, and so int13_wrapper would always chain to the original INT13 handler, which would obviously then fail.

Sorry you've spent so long debugging what turns out to be a (rare) regression!
