8192 x 4096 actually is supported by power of two hardware. The
only requirement for a TEXTURE_2D without NPOT abilities is that
each dimension (on its own) be a power of 2.
In general, something that might be worth checking out is the
largest free VRAM chunk via OpenGL Driver Monitor, since even with
512 MB of VRAM allocating 256 megs for a single object is not
necessarily a trivial operation (ie make sure you don't try and
allocate 2 of them!) The fact that the texture halfway works,
however, suggests that the large allocation was successful.
Please file a radar with a small test case if this indeed turns out
to be the case, along with an attachment of your hardware profile
that can reproduce the issue.
Thanks,
Chris

You could also try using a TEXTURE_RECTANGLE to see if that helps/
hurts and be sure mention any differences in your test case & bug
report.
