Subject: [2.6.35-rc1 regression] sysfs: cannot create duplicate filename ... XVR-600 related?

Booting 2.6.35-rc1 on a Sun Blade 2500 Red, I'm greeted with:

------------[ cut here ]------------
WARNING: at fs/sysfs/dir.c:451 sysfs_add_one+0x74/0x90()
sysfs: cannot create duplicate filename '/devices/root/f0079a58/pci0003:00/0003:00:02.0/slot'

(There are no interesting messages before or after this one.)

The device at 003:00:02.0 is a Sun XVR-600 graphics card, driven by
drivers/video/sunxvr500.c.  There was no such warning in 2.6.34 or
earlier kernels.
