R3000z and USB mouse

[Gene Czarcinski]

I have a recently manufactured Compaq R3000z laptop (Athlon64 processor) ... 
apparently one of the last with the 1920x1200 screen.

For some time now I have been trying to get the USB mouse to work.  I have 
both i386 and x86_64 everything installs of FC3 (as well as WinXP in a 
partition squeezed down to a reasonable size).  My problem is that same for 
both the i386 and x86_64 systems ... the USB mouse does not work (is not even 
recognized as present).  This has been bugzilla'ed as 
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=143895

The synaptics touchpad is recognized as a generic PS2 two-button mouse but is 
usable.

Now, I can get the USB mouse to work if I boot with acpi=off kernel parameter.  
But then the synaptic touchpad does not work and, even worse, with acpi=off 
cpuspeed (powernow-k8) and other stuff does not work.  Thus, running acpi=off 
is not a practical solution.

Besides searching the bugzilla.redhat.com, I also searched 
bugzilla.kernel.org.  On bugzilla.kernel.org I found a report indicating that 
there were some conflicts (problems) between USB support and the acpi code in 
2.6 ... identified but no solution proposed.  Recently, I found another 
report on bugzilla.kernel.org which sounded like my problem and had a 
proposed patch -- http://bugzilla.kernel.org/show_bug.cgi?id=3301  When I 
checked, I saw that it was included in the 2.6.10 kernel (available as 
kernel-2.6.10-1.727_FC3 in fc3 updates/testing.  However, this kernel has 
other problems in that rivafb segfaults (I load rivafb to get around the loss 
of sync in the text VTs).  Neverthenless, I was able to get around the rivafb 
problem so that I could test the "no_handshake=1" "fix" for ohci_hcd.  
Unfortunately, it fixed nothing and I still get:

OK, ...

1. Anyone else seeing problems trying to use a USB mouse on a Compaq R3000z or 
the HP more or less identical model?

2.  Anyone have any suggestions on how to get things to work (or getting more 
info)?

BTW, I am also aware that some individuals claim that the problem is with the 
F30 BIOS code which my laptop has install and that I should revert to the 
previous F21 BIOS.  I am very reluctant to changing BIOS code "backward" 
since this could break other things.

WinXP works with both the touchpad and the USB mouse as well as using acpi 
functionality so I suspect that it is possible ... just not in the 2.6 kernel 
yet.
