What do you _exactly_ want? Just boot and get a graphical console? Then
you may use the VESA-Framebuffer in the kernel. Note that the current
Vesa-FB driver can change the resolution only once, so the resolution is
fixed unless you start X with another driver or so.

If you mean, you want to detect the card and choose the appropriate
xfree driver, you should have a look on the Knoppix-CD. The
LinuxTag-Distribution (based on Knoppix-2.0) and knoppix-2.1beta can be
found on http://www.linuxtag.org/knoppix/

Depends on how do you use the CD. If there are permanently running
programs, started from the CD, you cannot change it.

gzip or bzip2 on the whole filesystem. Knoppix uses a kernel module
(cloop) to decompress the loop-mounted FS transparently.
