Using ELF sections for ramdisk

[David Goodenough <david.goodenough@btconnect.com>]

Does anyone have any good documentation for using ramdisks in ELF sections
in linux kernels.  In particular for Linux 2.6.  I have tried following the 
various howtos that google found for me, but they were all for 2.4 and they
do not seem to work properly on 2.6(.17).

Thanks

David
