kernel root= option ignored?

[Neal D. Becker]

I'm trying to boot with root=/dev/hda3, on my parallel ide, but the option
is being ignored.

(bhcompile at porky.build.redhat.com) (gcc version 3.4.1 20040831 (Red Hat
3.4.1-10)) #1 Wed Sep 1 18:01:20 EDT 2004
...
Sep 22 08:24:03 rpppc1 kernel: Kernel command line: ro root=/dev/hda3 rhgb
...
mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)

That's my lvm array, on sda/sdb that got mounted on root.
