I have an old Nova-T (not CI) and on every kernel/driver install I
uncomment this line. The card will then work if the modules are loaded,
unloaded and loaded again after a cold boot. On subsequent warm boots
this is not required.

I have had many different kernels from 2.4.x to 2.6.10rc2, the card has
been in two completely different machines (an MSI Hermes 650 and now a
VIA M10K based box) but none of this changes the behaviour.
