It also happens with a much older GeForce2 MX400.

Mine stopped blinking after switching to Jobermayr's drm-nouveau-kmp-desktop
and 3.0.0-2 (both installed at same time).

PS/2 connected, or USB? Mine are both USB with the 8600GT, but PS/2 on the old
NV11.

I only have a vague notion of the inner workings of X as they appear in the
logs, but I think you see the result of prioritization of drivers to try. It
prefers nvidia, regardless whether installed (which is never the case on any of
my systems), next tries nouveau, next nv, and last vesa. I always see their
*.sos listed, but only that actually used shows up in the capitalized repeats
show which is actually used, such as in this case (II) NOUVEAU(0):
