xfree delay when switched from console, laptop framebuffer

[knu]

Hi,

PROBLEM: when I switch to X from a console terminal (typically Alt+F7) the screen is freezing for about 10 seconds, rather too long.

CONFIG: laptop acer travelmate 800lci + USB wheel mouse, Knoppix 3.2 2003-09-05, original XFConfig-4

thanks
