JVarsoke uttered the immortal words:
Adding append="ramdisk_size=8192" to lilo.conf did it for me.
I can't see the point of upgrading to 2.6 yet though. The system I tested
2.6.0 on ran a lot slower and the sound card, which works beautifully with
the 2.4 kernel, wouldn't work.
I'll wait until 2.6 gets to 2.6.4 or later before I try it in anger.
