I was looking for such tools. This time I have already invested in a AGP graphics card for my system and it paid off. The lag is gone and I can use LyX 1.6 very smoothly again. FYI, I purchased a geforce 6200 card PNY VERTO GF 6200 AGP 256MB retail (G606200A8D24LPB). The card was easy to install - even on in a narrow AGP slot - and in Ubuntu 8.10 the nvidia proprietary driver got automatically pushed into the system. So, everything works fine now and thanks for sharing your comments.
