black screen, boot doesn't finish

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

I wanted to try the bugfix for PR 56718, but a kernel from a few
minutes ago doesn't finish booting for me. When it switched to
graphical console, the screen goes black and doesn't come back (before
that, it usually took about 2s then it continued booting).

My last working kernel is

-rwxr-xr-x  2 root  wheel   29481968 Feb 16 17:30 /netbsd.9.99.93d
(with a partial version of thorpej's bugfix for 56718)

The non-working one is

-rwxr-xr-x  2 root  wheel  29481848 Feb 17 19:59 /netbsd.9.99.93e
