Hi André,

sorry by mistake I pulled the obsolete patch out of my references.
Please follow Matthew Garret's brief instructions here:
http://www.codon.org.uk/~mjg59/gobi_loader/
Especially the "Note for kernel 2.6.32 or later" applies. The is a
link to the patch which I actually used earlier this year for Lucid.

Danilo's advice in his previous message seems to be even more helpful.
According to the launchpad ticket the patch has made into
"linux-backports-modules-2.6.32" for Lucid. At this time I would try
that first.

Cheers
Mike
