The update removes the particular speedup >which causes the difficulties. I recently heard from someone that one of the SpeedUp bugs was still causing a problem with a virtual width of 1024. I haven't seen this myself, but the stack trace he sent me does indicate one of the known SpeedUp bugs. I'd recommend that people using SpeedUp (on 386BSD) add: SpeedUp 0x37 to the vga256 section of their Xconfig.
