Seems this could introduce a risk of regression because it completely
removes the driver.  I'd lean towards not including this patch.

We were already carrying this patch in Karmic.

Results in  the rio, sx, and generic_serial modules not being built
and also CONFIG_RIO=m and CONFIG_SX=m being removed from
config.commong.ubuntu.  This could possibly lead to a regression.
Looking at some driver-stats I'd gathered a while ago I'd agree with the
upstream comment that there are a sparse number of users, and I only saw
1 hw profile mentioning the sx driver:

http://qa.ubuntu.com/reports/ogasawara/hwdb/driver-stats.html

But to be on the safe side, I'd say we not include this patch as well.
