For extra convenience also pass
--dhcp-range=10.20.30.10,10.20.30.100,6h
--dhcp-option=3,10.20.30.1
--dhcp-option=6,10.20.30.1
to dnsmasq, then your tablet will act as a DHCP server.

Fixable if you go to Settings -> Internet Connections and set WLAN
search interval to Never.

This could be because the SDK has kernel sources of version
2.6.28-20093908+0m5, and my device has kernel 2.6.28-20094102+0m5.
Any idea where to find the appropriate sources? GPL requirements etc.,
they ought to be out there somewhere.
FWIW I'm following the instructions at
http://wiki.maemo.org/Documentation/Maemo_5_Developer_Guide/Kernel_and_Debugging_Guide/Maemo_Kernel_Guide,
but it seems that those are a bit outdated
(maemo-sdk-rootstrap_5.0beta_armel.tgz? EXTRAVERSION=-maemo2?). I
would appreciate any feedback from people who have tried building kernel
modules with the final SDK.
