[Usual plea - Cc to me on replies]

Is there still any interest in modular IDE? It should cut kernel size down by 
appr. 150-200K (hard to say exactly, but IDE core + Ali driver is ~50K, given 
the number of IDE drivers I expect at least 150K) which should allow kernel 
to fit on floppy again. Besides, modern systems ususally come with SATA that 
is handled as SCSI anyway so IDE just bloats kernel. Handling should be 
pretty straightforward and could be unified with SCSI in this case.

Modular IDE was basically done 2 years ago and I run it on 2.6.15 without 
visible issues except hibernation. swsusp expects resume partition to be 
present quite early (before initrd); it is possible to initiate resume 
manually after drivers are loaded from initrd though,

If there is enough interest I could add support to initrd; BTW it also means 
that suspend to disk should not work with SCSI currently so it may be of some 
value anyway (but not as appealing to me :)
