Hmm... this might constrain the heap excessively if the SMT_TERMINAL
cutoff is at the wrong place (because there will be just enough SMT_FREE
to fit.)...

Could you give an example memory map where this would be a problem? I
not sure I understand what you mean. Perhaps someth...

[PATCH] Fix recognition of keeppxe option

chain.c32 has its own code to handle keeppxe. It looks like it's passing
the correct flag to syslinux_shuffle_boot_rm, but I wonder if the
problem is pxelinux_scan_memory is marking the PXE region as
SMT_TERMINAL?
