If this is BIOS version specific I'm going to be upset, but the general
case behaviour is that rfkill only works on the 901 if you either (a)
pass force=1 to pciehp (which you shouldn't) or (b) have native support
in a driver. My /guess/ is that you've got pciehp loaded, and there's
some kind of awkward race between it and eeepc-laptop.

BIOS bug. There's an explicit delay in the eee bios for some reason, and
I haven't found any straightforward way to avoid it.
