[2.4] sym2 module option to behave like 2.6

Several people have expressed dissatisfaction with their scsi drives rearranging when they switch between 2.4 and 2.6. It's particularly gruesome for people with an HP A500 as the internal discs swap positions.

I can't make the 2.6 driver behave like the 2.4 driver, so here's an
alternative: add an option to make the 2.4 driver detect hosts in the same order as the 2.6 driver. This patch is only compile tested, so is probably buggy.

"Next the statesmen will invent cheap lies, putting the blame upon 
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince 
himself that the war is just, and will thank God for the better sleep 
he enjoys after this process of grotesque self-deception." -- Mark Twain
