Marcelo,
It appears the block-device-cache/kswapd problem is indeed fixed in 2.4.23 (yay!).
To confuse matters RedHat has released an RPM with 2.4.20-24.7 which apparently contains later patches that include the fix. This can be confusing because their 2.4.21-4EL kernel is busted (WRT this bug). But, at least this way we can simply tell our RH-based customers to go grab the RPM.
Thanks, -chris
