I've a laptop too (Celeron@1000) and it's slower than my other P-II@266 with a normal video-card as regards graphics applications (like Bltiz ones). My laptop has also SHARED memory, that means VMEM is shared with system memory, so both the CPU and the GFX-chip use the same RAM and a bus arbiter is needed. Things are always slow even if I successfully allocate all the gfx in VMEM (I can set how much of system memory will be reserved as VMEM in BIOS settings).
