It can use the kernel's framebuffer if available, else a VBE 2.0 linear frame buffer can be utilized with no necessary kernel support.

Does it still requires > any type of support from the kernel? No. That is also an accelerated driver which uses the hardware features of the card to speed typical GUI drawing operations. The VESA framebuffer and/or the kernel framebuffer will usually not have any form of acceleration for graphics primitives. -- Ryan Underwood, <[EMAIL PROTECTED]>
