Acquire AGP and allocate AGP memory

This patch *really* should fix the bug.  The drmAddMap call fails because (in
the kernel) dev->agp->memory is NULL.  This field is set on the first call to
drm_agp_alloc.

With this patch (and the '#if 1' converted to '#if 0'), the drmAgpAlloc call
fails with EINVAL.  This happens when dev->agp->acquired is FALSE.  However,
with the patch as-is, the drmAgpAcquire call fails with EBUSY.  This happens
when dev->agp->acquired is TRUE.  How can dev->agp->acquired be both TRUE and
FALSE at the same time?

I really enjoy that I've wasted an entire work day on this bug. :(
