No, still no luck, seems like a bug to me.

So, you're running GENERIC.MP, but locally compiled.  What about that
INTERLDRM_GEM option you added, you wonder?  That option has had *NO
EFFECT* for over 8 months!  If you don't understand why you're
building and running a custom kernel, then you shouldn't be.  Just use
GENERIC.MP from the snapshots and save your own time and that of the
developers.

As for the error itself:

So, OpenBSD thinks the BIOS is broken.  Has HP released a BIOS update
for that machine?

I was not aware that inteldrm_gem has no effect for 8 months, in my
case x11 will freeze up if i try to run glxgears or even use mplayer
without inteldrm_gem option.

No HP has not released any BIOS update, i used to run Fedora 13 on my
laptop and it gave the same complaint. However, a kernel upgrade
cleared the error. This error has not caused any problems while
working on the laptop i just wanted to know if this is a hardware
fault or not.

new umsm device: Toshiba 3G HSDPA MiniCard

This makes the umsm driver recognize the WWAN module integrated in my
Dell Latitude D630... And it works as intended, using cuaU2 as device.

Before:

bce - not working

The bce(4) driver was removed from i386 GENERIC by Theo a few months ago because
it can only access 1GB ram. My Dell Latitude D520 has 2GB RAM and sure enough the 
driver did random things when I tried to use it back then. Ive looked at NetBSD
and they have an extra bus_dmatag_subregion() function for restricting the
memory range the driver accesses. Should this be implemented for OpenBSD?
