I am using the Dallas 1-wire bus with a custom host device. I don't see why
all the 1-wire drivers couldn't be built by default though.

Incidentally I'm also planning on experimenting with the new MMC driver in
kernel 2.6.24. How easy would it be to upgrade to this kernel? Is there a
good reason the Gumstix tree is still using 2.6.21?

(Explanation for the curious: Having got Bluetooth working I've discovered
that there's no fix for the regular HCI ACL timeouts (maybe they're
specific to my old ROK BT chipset). I'm switching to a Connex/wifistix for
connectivity, but that means I lose the MMC slot. It's so much more
convenient to boot from MMC rather than internal flash that I'm going to
try wiring an MMC card to GPIO and bit-banging to it.
