An unlikely idea, but might be worth a go, is the following:

1) get the nvidia version of radeontool:
git clone git://anongit.freedesktop.org/~stuart/radeontool; cd radeontool; make
2) start X using the nvidia proprietary driver
3) read the values of 0x9200, 0x9210, and 0x9220:
./radeontool regmatch 0x9200 (for all three registers)
make a note of the values
4) start X using the nouveau driver, set 0x9220, 0x9200, 0x9210 (in that order)
to the values read in step 3
./radeontool regset 0x9220 0xSOME_VALUE (for all three registers/values)
5) attempt to reproduce disappearing cursor using vt switching / resolution
changes as described in previous comments (note: don't restart X, that will
over-write the changes you made in step 4)
6) report here whether this game made any difference
