Hrm, the only noticeable difference between your Blade 1500
and mine is that on yours the generic vgapci(4) attaches to
the otherwise unsupported framebuffer. I gave such a setup
a try but that didn't trigger a panic (this actually wasn't
likely to). Could you please build and install a debugging
kernel in single user mode (a `mount -a` should re-mount /
read-write), i.e. a kernel with the following options:
makeoptions DEBUG=-g
options KDB
options DDB
If that kernel panics you should end up in the debugger
prompt. Please issue a `bt` there and provide its output.
