You don't have IDE support for your hard drive, and that's the reason
request-module [ide-disk] fails. In fact, you shouldn't see a
request-module at all.
In menuconfig, check "ATA/IDE/MFM/RLL support" -> "IDE, ATA and ATAPI
Block devices" -> "Include IDE/ATA-2 DISK support". I'll bet you have an
"M" there. Put a "*" there, and try again.
While you're at it, check "File systems", and make sure whatever you use
for a root filesystem has support compiled in. Also check "Block
devices" and make sure "Normal PC floppy disk support" has a "*" there.
Check out the newbiedoc on kernel compiling:

Let us know if any of that doesn't work or doesn't make sense.
