#905 SDL GUI startup failure
On Fedora Core 4 test 1, bochs 2.2.pre2 (also happens
with Fedora Core 3, bochs 2.1.1), setting
display_library to "sdl" results in startup failure.

You have keyboard mapping for the x gui enabled, but sdl needs a
different keymap. It should work when you disable keyboard mapping.

Yep, that seems to work, thanks.
Would it be possible to give a better error message about
what's the problem in this case? For example, if I remeber
correctly, using the wx conflig interface with a non-wx
display library gives a clear error message about what's
wrong with the configuration, something like that would be
useful.

The keyboard mapping feature is independant from the guis and I don't
want to add gui specific stuff there. This panic can also happen when
you try to write your own keymap table and there's a typo in it. I intend to
add "(wrong keymap ?)" to the existing message and add some
information about keymap problems in the docs.

I have improved the panic message and added some information about
panic messages in the user documentation.
