	Before I do this, I have a few questions; I know that the bulk
majority of the documentation for my questions may exist online or in
/usr/src/UPDATING, but I was just curious of the major changes that I
can expect between 6 and 7:

1. What scheduler is currently the most complete for SMP/multi-core
capable processors?
2. Do I need to add some sort of compatibility layer for 6 going to 7
(similar to compat_5)?
3. What are (briefly) some of the major changes for the ABI/API going
from 6 to 7? Someone mentioned some changes to the ABI when I emailed
the hackers@ list previously, so I was just curious.
4. How is SATA support for SIS motherboards under 7? Decent?
5. Is 7 running gcc-4.x?

	Thanks!
