PVR-related errors in dmesg are due to something wrong in setting up memory exchange with graphics controller. I guess framebuffer is messing up something. Do you really need a framebuffer for this kernel?

Not anymore, updated zImage (and corresponding modules deb) are in SVN now (as well as the updated hotspot_config.patch)

gc.set_string('/apps/mobilehotspot/encryption_algo', 'WEP')
gc.set_string('/apps/mobilehotspot/encryption_key', 'key bytes')

note that the encryption key here is the actual bytes of the key, hotspot_backend.py will take care of hex-encoding them for iwconfig.

Also note that hotsport_backend.py will padd the key with zeroes to get it to exactly 13 bytes (and in case your set key is longer than 13 bytes it will trim it down ot 13bytes). You can see the exact hex-encoded key in hotspot_backend.py output when it calls iwconfig.

Note that my Mac laptop refused to even see the N900 hotspot when encryption was enabled so it might be that this does not actually work even if from the device POV it seems to.

To disable/re-enable encryption you can just unset/set the encryption_algo config key.

Started work on the GUI, now you can choose the connection to share via it.
Does that mean an easily installable app that I can install from app manager soon?

The one and only thing missing from my old symbian phone is Joikuspot

it depends on many things, pushing something using a custom kernel the the normal maemo-extras will take quite a bit of testing.

if you'd like help please see the project homepage for installatioh instructions.

I have rebuilt a kernel for PR1.1 with lots of .kos.

http://www.freemoe.org/users/jebba/d.../binary-armel/
http://www.freemoe.org/users/jebba/jebba.install

I'm getting quite a bunch of reboots with it though, which I didn't have before...

I was getting reboots too, although they might be unrelated to yours since I compiled my own kernel. For some reason, when my laptop associates with my phone in ad-hoc mode the mac80211 driver decides to only use one rate, which causes the driver to access uninitialized memory and panic.

This is the quick fix I used. I don't understand enough about the mac80211 driver to figure out quickly why only one rate is listed, but this stops the bugcheck and gets tethering working.

Code:
diff -U3 ~/old/rc80211_minstrel rc80211_minstrel.c
--- /home/jperry/old/min_OLD    2010-02-09 02:04:27.000000000 -0800

                mi->sample_column++;
                if (mi->sample_column >= SAMPLE_COLUMNS)
And here's the OOPS!

Could you post a HOWTO on what actually needs to be done to get oops logs out of the device (including any changes needed to the kernel config).
