Hardly on a shader model 1 card, and even not all shader model 3 cards do vertex texturing (I think NVIDIA does, but ATI not).
I use R2VB on the ATI cards instead.

From OpenGL's vertex-shader specs:
For me (GF6600GT), this value shows 512 which makes 128 vectors which makes 32 4x4 matrices or 42 4x3 matrices. Correct me if I'm still wrong, but this does read in the specs.

The value is 512, which makes 512 vectors. One register is 4 floats wide.

Oh I see the confusion now, some of us are talking about constant registers holding 4 values a piece, and some are talking about the number of values period.
Personally I find it easier to discuss things in terms of the vec4 registers.
Btw, I thought pixel shader 3.0 hardware was required to support a total of 256 constant registers (float, int and bool)?

Ok, I took a look with the DXCapsViewer and indeed, it shows 256 vertex shader constants, which is in float4, right?
Now I just wonder why the OpenGL implementation has half less registers? Same hardware and everything. Or are they cheating on the fact that they'd have 256 registers on DX?
