In GTA San Andreas for PS2 Rockstar used RenderWare's Pipeline Delivery System (RpPDS) that was introduced with RW 3.5 to create custom pipelines. This page is about Rockstar's custom pipelines specifically, PS2 pipelines in general are described here: PS2All.
All of these pipelines are initialized in init.pm/nm (see PS2 Code Overlay) so the addresses below are only valid if the init code has been loaded into memory. Addresses refer to SLES_525.41 and init.pm.
All object pipelines have even IDs, material pipelines have odd IDs.

Building Pipelines
All of these pipelines use the building VU1 code.

53F20089 (template @ 627510) clusters: 6 6D00000D (R* xyzw) 7 6500000D (R* uv) 8 6E00000D (R* normal) 9 6C00000D (skin data) stride: 4 vertexCount: 0x2e primCount: 0x10 vifOffset: 0xC0
Data format and VU1 code
Normals are scaled by 128, UV coordinates by 4096.
Vertices are scaled by 128 in the building code, otherwise by 1024.
The W field of the xyzw cluster is 0x0000 or 0x8000 and written to the ADC field of the XYZF register. 0x8000 inhibits the draw kick for this vertex.
For each vertex skin value the lower 10 bits are the bone matrix offset, the upper 22 bits are the upper part of an IEEE-float.
The bone matrix offset can be converted to a bone index like this: i = off == 0 ? 0 : off/4 - 1
(Actually all 32 bits are interpreted as IEEE floats, bone transformation isn't sensitive to little changes in the lower bits. Also all lower 16 bits are used as the bone offset but since the VU1 memory has only 16kb and the memory is qword-addressed, an address is only 10 bits long and the upper bits are ignored. The offsets are added to the start of the bone matrix array (which starts at 0x2d0) -4: so they're added to 0x2cc)

(NB: the disassembler has a bug and always disassembles div instructs as 'div q,vf00w,vf00x')
