Kernel drivers...
... are the reason that even Cyanogen can't develop their newest for the original HTC Desire - if the manufacturer doesn't release them there's not much to do except hope that your chef of choice still keeps cooking up Gingerbread in the ROM kitchen.
OTOH this kernel fault is hitting millions so if Samsung fix it on one handset there's a good chance it'll work across them all (providing it's low-level enough) - Galaxy S2 and up with their own CPU (as opposed to Qualcomm like in US S3s). They've rolled out kernel patches before without needing to fuss with Network kludge, so I wouldn't give up hope. I reckon if they've rolled 4.x out for the handset it'll likely be covered.
Then again, my record on winning bets is jot good - might as well bet against me just to be sure... ;-)
