I think it's unlikely without the sysfs interface.

The bug has been there since 2.6.25 but nobody else seems
to have reported it. Is the general policy to fix all
oopses that *could* appear? I'd send it for 2.6.27-stable,
since that's got the sysfs hooks. And older kernels if
bug likelihood isn't a major concern.
