do you have chance to try current tip/master
http://people.redhat.com/mingo/tip.git/readme.txt
or 2.6.29-rcX
plus following patch?

or can you check if there is update fw for your LSI card?

[PATCH] mpt: fix enable lsi sas to use msi as default

Impact: fix bug

the third param in module_param(,,) is perm instead of default value.
we still need to assign default at first.
