Is there a kernel flag to tweak or disable the Spectrum console?

If I boot with my spectrum installed, the console comes up on a
screenmode that my plain-jane VGA monitor doesn't like. In the interim,
I've removed the spectrum and am running the deinterlaced output of my
3000 straight to the monitor.

I'd like to be able to either change the spectrum console mode such that
it uses a generic VGA scanrate, or disable the spectrum console
altogether.. Are there kernel flags to do this? (BTW, where are kernel
flags documented? Moreover, where can I get kernel sources/objects?)

Thanks in advance.
