What float/int casts? out is an int* and data is a char*, so where's the float?
This also looked interesting:

And with regards to the vbo code:

I switched to tcl_mode=1 by default a while ago because I thought it might be
faster (hardware vs software), and the feature is still buggy when ARB_vbo is
enabled. This is basically why I tried using valgrind - to see if anything
showed up in the software vbo code.
Incidentally, I saw that the r300 implements vbos in hardware. Is this an extra
feature of the R300 hardware, or could the R200 hardware do this too?
