though you wrote about /dev/hda*, which means you should be a bit more carefull if you used the IDE drivers (under ATA/ATAPI/.... support, thats the "CONFIG_IDE" option) and disabled the CONFIG_IDE options, you have to enable it under Serial ATA (prod) and Parallel ATA (experimental) drivers (CONFIG_ATA) and also your device might get renamed to sd* instead of hd* (I don't know, I have only a cdrom, that becomes sr0 ;) But I think that the real problem was with those SYSFS_DEPRECATED options, so you might be able to get things working with just disabling those and leaving IDE as it was... btw, I found this bug afterwards: http://bugs.gentoo.org/show_bug.cgi?id=302173 yoyo
