This one seems fixed now, the kernel only fails at link time:

videodev_exit might come from the non-essential planb
driver (video input), but the ADB bus is pretty much
mandatory on a 7500 (in particular when no serial
console is available :-)

isn't the save_flags/cli/restore_flags supposed to be
local_irq_save/local_irq_restore(flags) now ? (curious,
as I had a save_flags in pm3fb...)

Thanks in advance for any help,
