Applied the rnn stuff.

This is caused by the way TEX_ENABLE is defined...
<stripe length="4" stride="64">
<doc> Texture units. </doc>
<!-- ... -->
<reg32 offset="0x1b0c" name="TEX_ENABLE">
<!-- ... -->
</reg32>
</stripe>
TEX_ENABLE is actually a singular register defined within an anonymous
stripe with length 4. If TEX_ENABLE was itself an array-register,
NV20_3D_TEX_ENABLE__LEN would be its length. What you want is the length
of the stripe, which doesn't have a name, and hence doesn't have a define.
I'd suggest changing the stripe's name to TEX, and nuking TEX_ prefix from
the regs inside it: you'll end up with NV20_3D_TEX__LEN defined to 4, and
the effective names of stuff inside it will be unchanged.
