#10 remove bashisms

[rob0214]

hi,

i'm working in an embedded environment. it would be
nice to be able to not have to use bash, and use ash
provided by busybox (since bash eats about 1 Mb of my
16 Mb flash).

i think the only thing that's needed to be removed is
the arithmetic expansions, ie:

PCI_ANY=$((0xffffffffff))

causes problems with ash/busybox.

hotplug scripts are obsolete. use mdev or udev.
