Adding this parameter didn't have a noticeable effect.

Directly after loading the kernel, so it seems.  There's a line near the
beginning of /var/log/messages right after mounting of initrd referring
to it:

    vesafb: probe of vesafb0 failed with error -6

As it turns out, I needn't have worried so much about this.  I was
worried about vesafb conflicting with sisfb which I was considering
loading later on.  However, as long as vesafb was not `active' (i.e.,
vga=normal passed to kernel), a later `modprobe sisfb' didn't cause any
problems.

Until next time, Colin.
