First one is userspace bug, i need to look into the second one.
ie we were lucky the hw didn't lockup without depth buffer and
depth test enabled.

As upstream doesn't consider the first to be a kernel issue, I guess you
should just list the second.

OK, if the failure is due to userspace is doing Very Bad Things(tm),
catching that seems reasonable.

Nevertheless, even if it happened by luck, the result was (ostensibly)
working programs that suddenly break once one "upgrades" to the latest
kernel. If userspace can't be fixed before 2.6.34 is released, perhaps
a less cryptic log message would be appropriate?
