Sorry it didn't work out better. If the module loaded and created device files I'd guess it's compatible enough that it ought to work, but I really don't know offhand what subtle differences exist between n800 and n810 kernel builds. Still, my bet is some detail in how the server is started and/or some little bit of config file verbiage. Hope you have more luck next weekend!

FWIW my uname -a string is:
Linux andy-n810 2.6.21-omap1 #2 Tue Oct 14 11:25:25 EEST 2008 armv6l unknown

So I wonder if you're running a 2.6.21-omap1 flavor of OS.
