Hmm, that's strange I tried it on several adapters (PCI and ISA), and
they all worked fine. What kind of adapter do you have? Obviously, this:

        p = (unsigned short *)(((ORIG_VIDEO_MODE == 7) ? 0xb0000 : 0xb8000) +
                               + VGA_OFFSET);

somehow goes wrong. It shouldn't, because otherwise the rest of console.c
wouldn't work, so something _is_ wrong.

Could you try something like this:

char buf[128];

sprintf(buf, "VGA at %p\n", p);
vt_console_print(NULL, buf, strlen(buf));

In con_is_present() ?

I'll have another look at it tomorrow...

Mike.
