Hmmm... The system should alias the 192 byte cache to the 256 sized one.
What kernel version is this? We could have broken this in 2.6.25 with the
addtional flags that were added. But then it should be okay again for
2.6.26-rcX which removed those additional flags. If this is indeed the
case then we need a fix for stable and mainline is fine.
