nvidia/nouveau problems

I got a new Sandy Bridge i7 laptop with nvidia/optimus graphics.
I managed to install the new KDE beta, after a few problems.
However, there seems to be some issues with nouvaeu trying to
start up: One issue is errors messages and slowness starting up:

First I get this console message:
mkdir: cannot create directory `/run': File exists

Then I get these errors from nouveau:

Pointer to BIT loadval table invalid
i2c wr fail: -6
PGRAPH: unsupported chipset, please reported

Then it hangs for a long time (many minutes), before I
finally bet a KDE login screen.

After KDE starts up, things mostly work, but some fan is
going continuously, even when the system is idle.  Perhaps the GPU fan?

My preference would be to just use integrated graphics, and
completely disable the nvidia graphics.  Unfortunately, there
doesn't seem to be a way to do that from the BIOS, at least
not the visible BIOS control settings.

Googling hasn't found any good suggests so far.
I've tried "blacklist nouveau" in both blacklist.conf
and in blacklist-nouvaeu.conf.  I also added rdblacklist=nouveau
to the kernel line in grub.conf.

One suggestion I've seen is to prm -e the nouveau driver.
