Identical problem here, trying to connect to a myTouch 3G running Android 2.1 (cyanogenmod) via bluetooth tether. Running on an MSI U-100 laptop. Connection used to work without issues on the linux- image-2.6.32-24-generic kernel. Running lts maverick backport in lucid lynx; kernel is:
Linux eugbook 2.6.35-9-generic #14~lucid1-Ubuntu SMP Sun Jul 18 13:11:45 UTC 2010 i686 GNU/Linux (also had the issue with .35-7).
