Tejun-I find the allocation always above 32bit with the following tests

1) kernel-2.6.24-rc5 + the 32 bit limiting patch that you provided in a
previous posting.
2) vanilla-2.6.24-rc5.

Hello,
I am seeing that this doesn't fix a Dell PowerEdge T105 which has the CK804

This system has a "HL-DT-ST" DVD-ROM (See dmesg with this posting) attached to
