This is bizarre.  What is the purpose of placing a known broken driver
in the kernel, regardless of the issue that causes it to be broken?
It seems logical to me that any issue preventing a driver from
functioning should be solved before placing a driver in the kernel,
not afterwards.

Yes, for the record, the 10.0.7a driver worked just fine when compiled
as a module.  Works exactly as advertised.  Which makes me happy.  But
i still feel a bit burned because i thought that a driver placed in
the kernel would be ready for using, that i wouldn't have to use an
external driver, since there's one in the kernel.
