Trouble is, vertex array data is put into the vertex/indirect buffers, and those are 64k a piece - that's good enough for an array size up to 4096 (float4) entries (actually the driver currently doesn't set this limit (Const.MaxArrayLockSize), it probably should, but the default of 3000 works too). There are other limits currently too, for instance the indices are only 16 bits, and you can only emit somewhat below 32k of them at once (or below 16k if you'd use 32bit indices, though 32bit indices might be r200 only). This is actually afaik a hard limit of r100 chips, r200 could do the same as r300, with putting the indices into a separate buffer.
