Is it possible to build a kernel that outputs to the console but accepts
input from the HIL keyboard?

After booting the kernel over the network and mounting the miniroot
filesystem from the hard disk the kernel crashes, when I'm pressing a
key on my HIL keyboard:

Terminal type? [hp300h] trap: bad kernel read access at 0x4
trap type 8, code = 0x505, v = 0x4
kernel program counter = 0xd73cc
kernel: MMU fault trap
pid = -1, pc = 000D73CC, ps = 2100, sfc = 1, dfc = 1

I'm using miniroot-14.fs.  The kernel outputs the following messages:
