Hmm, downloadable charsets is also in syscons, permanent mapping also
(allthough system wide not per console, easily changed though)
512 chars, no not yet :)

Yep, because now we are talking features that doesn't work on all
hardware and that is The Wrong Thing because:
1. There is no end to the supportproblem on this, and the percentage
of supported hardware is falling by the minute.
2. The kernel size will explode if just a tiny fraction of the possible
video hardware is to be supported.

So, that means we are stuck with the unlucky situation we have now,
for time and ever :(

I havn't forgot, but I'm still not convinced that it is a good idea,
I'd rather have a modular console driver, that I could modify the
behavior of by loading different modules.
*sigh*
