:) Thanks, that indeed works for me.  But I really don't expect you to
maintain "even uglier workarounds" just to please my development
machine, which I hope to upgrade soon (in Debian terms :).

Just to wander even farther from the original subject line, the ELF
format makes symbolic debugging possible.

$ qemu -fda extlinux.144 -serial stdio -s -S
$ gdb extlinux.elf
(gdb) set architecture i8086 
(gdb) target remote localhost:1234

gets me pretty far, but I can't get a meaningful backtrace, as if
GDB didn't recognize the stack correctly.  What do I miss?
