When booting, I get the following error(?) message.

Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 149M
agpgart: Unsupported Via chipset (device id: 0296), you might want to try agp_try_unsupported=1.
agpgart: no supported devices found.
The only way this affects X11's behaviour (afaik) is that switching between tty and X11 is really slow.

Where should I put the "agp_try_unsupported=1" ?
