Panic booting NetBSD 7.0 BETA drmkms on amd64

[Jimmy Johansson <sawedoff.shotgun.debugging%gmail.com@localhost>]

Hi,

I decided to try out NetBSD 7.0 BETA today. I had no trouble installing 
and booting a generic kernel, although I didn't get any DRM, but I guess 
that is to be expected?

Machine: NetBSD 7.0_BETA amd64 x86_64

After that I compiled a drmkms kernel from sources checked out today and 
got a kernel panic at boot. I have no serial port in the machine, but I 
wrote down what I could. The panic and working generic dmesg.boot follows:

Panic:
