Yes it did.
Coming to think of it, make exited with an error during the final step of 
kernel compilation - "make modules_install" because of dependancy issues with 
some *pmcia* and *mtd* modules. Therefore the resulting initrd.img created 
from /lib/modules/2.4.21 directory must have been lacking in some aspect.

Building disk & filesystem drivers directly into the kernel as per above 
instructions and forgetting about initrd.img did the trick.

atlas:~# uname -a
Linux atlas 2.4.21 #3 Tue Aug 26 20:01:03 EAT 2003 i686 unknown
