I attached a patch that fixes the problem. It introduces a new
TCL_FALLBACK if there are too many vertices to fit into one DMA buffer.
Looks kind of hackish to me. Does anyone have a better idea? Comments?

Mesa should respect ctx->Const.MaxArrayVertices, which should be being set in radeon_context.c --- it may be that this code is disabled - can you check that & try turning it back on.

Found it: radeon_context.c around line 375:
/*     ctx->Const.MaxArrayLockSize =  */
/*        MIN2( ctx->Const.MaxArrayLockSize, */
/*  	    RADEON_BUFFER_SIZE / RADEON_MAX_TCL_VERTSIZE ); */

And then there is the definition of RADEON_MAX_TCL_VERTSIZE in
radeon_tcl.h which is (4*4). However, I saw vertex_size==24! Maybe the
real MAX_TCL_VERTSIZE is even bigger?

Yes it is, because we went back to using vertexes instead of individual arrays, but forgot to reset this max value. I've committed the fix.
