You probably want to modify the /linuxrc and /bin/startfpga scripts
in the initrd. They are pretty simple scripts and should be fairly
self-explanatory. You will want to remove the insmod lines for the
drivers for the FPGA logic you are replacing. (video, serial,
ethernet (open_eth), and SD card)
You may be able to rmmod the modules also and the load your
bitstream, but I'm not positive all the Linux drivers can be rmmod'ed
(esp. the video drivers) gracefully.
