760CD: my mouse hates my CD-ROM

[Frank Sheeran <Frank.Sheeran@ska.com>]

Back when I thought my CD-ROM might be EIDE or SCSI, and I tried the pre-built
kernels with support for those kinds of CD-ROMs, it (of course) didn't work.
 
After I was told my nipple was a "ps/2", I relinked /dev/mouse and changed my
boot scripts to gpm -t ps2 and XF86Config likewise.  The mouse worked fine, on
both the console and X...
 
Then, I hear that the CD-ROM is an "ATAPI".  Trivial!  Just take the ATAPI
pre-built kernel!  It didn't auto-detect, but *did* find it for the next boot.

And the mouse stopped working.  "Cannot open mouse (Device or resource busy)"
says both startx and gpm.  There is not a gpm running in the background.
 
Ahh, the pre-built ATAPI kernel had no ps2 support, I guessed.  I compiled a
new kernel with both ATAPI and ps2 support.  Run it, still see the CD, still
can't talk to mouse.  Boot with old boot disk.  No more CD, hello mouse....

When I boot the custom kernel with the CD player installed, the mouse is
always "busy".
 
Same kernel booted with floppy drive in lets the mouse work, but CD-ROM isn't
recognized even if I hot-swap it.
 
I took the floppy mount out of my fstab, thinking the failed probing for it
when its not installed was related.  I get the CD-ROM, but still lose the
mouse this way.

In summary: if I boot a kernel that can recognize my CD-ROM, when it is
installed, I am mouse-less.  If I boot a kernel that can't recognize my
CD-ROM, or my CD_ROM player is physically gone, then I have a mouse.
 
I've got to admit, this isn't the worst problem to have, but...
What the flock is going on here?
