Yes, I think so, that's what I meant when I wrote:

More specifically, here is the sequence of commands I used, extracted
from my shell history:

mkdir STABLE
cd STABLE
svn co svn://svn.freebsd.org/base/stable/9
cd 9/sys
svn merge -c 
235356,235359,235362,235365,235366,235372,235375,235776,235782,235783,235846,235847,235859,235925
 svn://svn.freebsd.org/base/head/sys
cd ..
vim sys/dev/acpi_support/acpi_ibm.c     # adding "LEN0068"
make buildworld buildkernel
make installworld installkernel
mergemaster -FUi
shutdown -r now

The list of revisions to merge is taken directly from
http://wiki.freebsd.org/Intel_GPU where the patch used to be.
There was only one reported merge conflict, caused by a line a context
from CURRENT that didn't exist in STABLE, but since it was only adding
declaration lines, it was trivially solved.

Now maybe I'm missing some code, maybe I made a mistake copying the
revision numbers (I've only checked them 3 times, but found no mismatch),
maybe the wiki page is wrong. That's why I'm publicly asking for help,
at least for diagnosis.

Or maybe I made no mistake and intel integrated GPU is just that bad
(though performance in Windows does not really hint that way).


Thanks for your help,
Natacha
