Too bad. External binary modules never have, and never will hold back
development. NVIDIA need to issue driver updates that work accordingly.

2.6.6 will have 4k stack patch merged.

Yes. Supporting both makes zero sense other than to support binary
modules.  Nvidia made an assumption about kernel abi (not that there is
one per se), that turned out to be no longer true.

Yes.

They'll have to soon anyway, it's in mainline since this afternoon, so
will show up in 2.6.6rc1

Where they'll find exactly the same issue. The options are..

1) Stay with an earlier kernel.
2) Wait for NVIDIA to fix their drivers.
