Exactly. And sorry if I've misssed earlier discussions, I just discovered
this morning that I had been disconnected from linuxppc-dev for at least 3
weeks, perhaps more (probably at the time our computer staff upgraded the
mail server and all mail was explicitly refused for 2 days, strangely
linuxppc-commit did not expel me). I' too busy on other fronts now to
catch up rading the archives....

This said, i should try one day to upgrade my bootloader for 2.4.xx, after
all, AFAICT no other bootloader includes an x86 BIOS ROM emulator.
The code is still on vlab1.iram.es or people who want to play with it but
it is broken since 2.2.17 or so (I succeeded in booting 2.4.0, however).
