well, I'm still not sure whether Oracle software is compatible with raw-io patch in linux kernel, please let me know how are you doing with that.

devfs is a very usable patch compatible with most of devices (including LVM) and software (I can only think of vmware that doesn't run with vmware). it saves a lot of inodes in /dev and contains only devices really present in the system and uses intelligent backward-compatible naming scheme (so you can still use inodes like /dev/sda etc) present in many modern UN*X flavors (like Solaris, e.g.). You should give it at lease a chance before saying you use it only because of raw-devices ;)
