I woul suspect that /lib is corrupt. I had a similiar problem on a debian install with reiserfs while testing for power outages. Also afaik ext3 is less resilient than jfs.
In rescue mode, running grep gives a segfault. Lately, even running mount gives a segfault. Mount was ok till yesterday.
From what I know, proc is mounted by the kernel on /proc. All that is
required is the existence of a proc directory in /. I suspect something wrong with the kernel mechanism that mounts proc. I wanted to build a new kernel, but I don't see how that can be done from the rescue mode. The rpm command would complain of missing modules and compiling a tarball would be even more difficult.
Your userspace seems broken to me. I doubt it has anything to do with the kernel.
If you notice, the reason /proc isn't being mounted by the init script is because grep segfaults. I wonder if there is something like Gentoo's revdep-rebuild for Red Hat.
I'd run an fsck to start with. If necessary, restore from the superblock backup. Then I'd reinstall glibc and the lib packages.
