11 June is just about the date that the updates were all merged into
9-Stable. I suggesting updating sources to at least 15 Jun (or, better
still, today) and buidl that. No additional patches are needed. DO NOT
SET "WITH_KMS"! KMS is ONLY for Intel CPU/GPU processors. You can give
it a try WITH_NEW_XORG, though. If you don't have KMS, you will not
have i915-kms.ko, so don't worry. (Maybe someone will volunteer to
write an AMD/ATi KMS driver some day, but no one has to date.)

You might try an initial startx with no Xorg.conf file. It usually
works. You probably won't have a need for acpi_call, either, and it is
from the acpi_call port and not part of the base system. It lets you
poke at ACPI paramters.
