Au contraire; using 'olpc-upgrade ubuntu' gives you ubuntu with the
2.6.22-20080312.2.olpc.f3687aa7e09fd65 kernel (same kernel as build
703), and tail /var/log/messages certainly shows:

libertas: eth0: Marvell WLAN 802.11 adapter
libertas: PREP_CMD: command 0x0074 failed: 2
usb8xxx: Firmware does not seem to support PS mode
usbcore: registered new interface driver usb8xxx

So these failures are not isolated to 2.6.25, and are probably not the
direct cause of udevsettle taking such a long time.
