To be pedantic (I'm not trying to split hairs, just trying not to
dismiss things out of hand!), there could be a bug in
1. 2.6.21.5 (so, perhaps 2.6.21 might have worked)
2. the kernel config system - maybe something got turned off
3. maybe something new in 2.6.21{,.5} is selected by default but
doesn't work on your hardware.
Assuming you still have the .config that you _created_ (you did run
'make oldconfig', right?), try diffing it against the config from
2.6.20.3 to see what has changed. First, you are looking for
changes you didn't expect to see (particularly, things no longer
selected). After that, look at what new things were turned on.
If nothing jumps out at you, I'd try testing with 2.6.21 itself, to
see if the problem was new in 2.6.21 or is from one of the -stable
updates.
I'm not on an x86 box at the moment so I can't review my own dmesg,
but things I would look at are sysfs compatability (I think that was
new in 2.6.21, you almost certainly want it turned on), filesystems
(in case any dropped out), and SATA/IDE drivers - I can't remember
which kernel changed all the options for SATA and libata, maybe it
was already changed in 2.6.20, but this sounds like the sort of
result you might get without the correct disk driver(s).

Good.

I don't know for certain, but I think it's definitely a
possibility.
