Keith,

If you're new to SSD trim, you might want to read this SUSE wiki page.

http://en.opensuse.org/SDB:SSD_discard_%28trim%29_support

(I wrote most of it, but I tried to keep it factual.)

For reference, it talks some about opensuse 11.2 and 11.3 but you can
just think of those as older kernels.  (11.4 just came out and has a
2.6.37 kernel.)
