My CD contains a LinuxDriver/English/en.tgz tarball which contains a
BearPaw100CU_EN-1.1.0-1.i386.rpm file.  If you install this, you will
find the firmware in /usr/local/bin/ps1fw.usb

However, this firmware is a bit different from the one I have in my
WinXP directory (28 bytes shorter).  From the timestamps on the CD, it
looks like the one in the WinXP directory might be the newer of the
two.  MD5:

86b34f960429b05e2ad7cd2b5c293b83  PS1fw.usb  (WinXP version)
9def003d34cd8334dc09ba5c7c2a6d18  ps1fw.usb  (LinuxDriver version)

PS1fw.usb is 8032 bytes, ps1fw.usb is 8004 bytes long.  The xdelta
between the two is 1709 bytes long, so it looks like they are fairly
different.
