I, too, have similar problems.

I have a Pavilion zv5340us notebook - AMD64, Broadcom 802.11 built-in, etc.
I had written before about problem with the button at the top of the keyboard that activates/deactivates the wireless device.  I had gotten it all working nicely...

...but then I added more memory.  The notebook has 2 memory "slots", one is easily reachable behind an access panel, the other requires some disassembly to get to the slot under the keyboard.  I replaced the easily reachable 256MB memory module with a 1GB module - the other slot still has a 256MB module.

Since then, my machine would hang when starting Driverloader during boot if the device was activated (device activation state is controlled by the button above the keyboard and is persistent between reboots/power off-on).  This on kernel 2.6.8-24.11.  If the device is off during boot the machine comes up fine, but pressing the button to activate the wireless device causes the system to lockup.

Yesterday I dl'd the newest kernel 2.6.11 and with the fix mentioned in a post earlier today, I tried driverloader with it.

Now, instead of locking up, the system has its CPU pegged at ~100%.  But I was able to see that a process called "kdldrd/dpc" was eating up all this usage.  As with the most recent post that I've forwarded here, the keyboard input is strange.  In my case, same letters typed with other letters in between got jumbled.  For example, I would type "dldrconfig" and what showed up on screen a few seconds later was "ddlrconfig".  Or  "10802" became "10082".   Unlike the post I forwarded, mine is a single CPU system.

With the 2.6.11 kernel, I could press the button to deactivate the wireless device and the system would go back to normal (CPU usage OK and keyboard input OK).  On the 2.6.8-24.11 kernel, once the system locked up, deactivating the wireless device did not free up the system.
