Work on eddie:
LVM filesystems newfs'ed, /usr/src/sys copied and
cvs -q upd -dPAed, new kernel built.
Boot attempt with i915drmkms enabled, will still
blank the screen but now I can ssh into eddie and grab the error
messages from dmesg. Patch for the kernel from the
mailing list didn't improve things. Also built a kernel with the
netbsd-6 i915drm driver (now classified as "legacy").
Can run X11 but it won't figure out the size of the 1024x600
display; it uses 800x600 instead.
Starting from the wmieeepc0 device in the boot
messages, I found src/sys/dev/acpi/wmi/wmi_eeepc.c and
think that it may be straight forward to add a few hotkeys which
are not recognized as of now. And, one day later, I found
/usr/src/sys/dev/acpi/asus_acpi.c which holds those
key definitions, too. Both drivers are documented and part of the
generic kernel. An asus0 device doesn't show up in the
boot messages, though.
Looks like I should learn a few basics about this new-fangled ACPI stuff.
