Kernels later than 2.6.12-1.1456_FC4 hang during boot

Description of problem:
I've got an HP nc6230 laptop, and whenever I boot any FC4 kernel newer than 2.6.12-1.1456_FC4, it hangs on boot. With any FC4 kernel earlier than that (including .1456), the kernel boots just fine. I've copied down the screens after booting 2.4.14-1.1636_FC4 the following four ways:
o with "quiet" and "rhgb" on the kernel command-line
o without "quiet" and "rhgb" on the kernel command-line
o with "pci=routeirq" on the kernel command-line
o and, finally, with "acpi=off" on the kernel command-line
In each of these cases, the kernel hangs on boot. I'll attach a file to this bug that contains what was on the screen during each hang. (Any typos are mine, as I copied these by hand.)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot to kernel later than 2.6.12-1.1456_FC4 on an HP nc6320 laptop
2. Watch the kernel hang on boot
Actual Results: The kernel hung
Expected Results: I guess, I'd expect the kernel not to hang :-)
I've tried every version of the kernel between 2.6.12-1.1456_FC4 and 2.4.14-1.1636_FC4, and they all behave similarly. I'm also going to attach a file containing the output of "lspci -vvv" and "lspci -nvvv" from the 2.6.12-1.1456_FC4 kernel.
I've also tried updating the laptop to the newest BIOS, in case it's a problem with the BIOS. After updating the BIOS, it still behaves the same way.

Boot messages on screen during hang
This file lists what was on the screen during each of the tries.

Output of "lspci" on a working kernel
This file contains the output of "uname -a", "lspci -vvv", and "lspci -nvvv" on
a working kernel. I thought it might be useful.
If it helps at all, I'd be willing to do more testing using this laptop, either
running different kernels, giving the output of other commands, disabling
on-board resources in the BIOS (if possible), etc.
Also, it appears that this bug *might* be related to 170205, but it seems kind
of a stretch.
Mass update to all FC4 bugs:
An update has been released (2.6.14-1.1637_FC4) which rebases to a new upstream
kernel (18.104.22.168). As there were ~3500 changes upstream between this and the
previous kernel, it's possible your bug has been fixed already.
Please retest with this update, and update this bug if necessary.
