the aic7xxx_old driver is in deep maintenance; I don't think anyone can
actually test changes to it anymore, so we just keep it around unchanged
for the odd really old card that can't be driven by the current driver.
For this reason, we tend only to do tested bug fixes to it because
no-one will notice if any error is introduced.

mvsas has a maintainer: poke them harder and aic94xx is currently
maintainerless, so it will depend on someone finding the time to test.
