If you don't want dynamic memory allocation for framebuffer and neither do you want it in the user space, All you need is to pass memmap = <size>$<start address> to the kernel and then write a kernel module module where you ioremap that physical address space.
This is just like any other device driver where device registers are mapped.
Thanks for your answers, it sounds very straightforward. One more question: Currently I'm using the book Linux Device Drivers 3rd Edition (2005) as a reference, and it's discussing Kernel 2.6.10. Do you think that's still okay, or should I get/buy a more recent book on this topic, and which would you recommend? -- Grüße, Kai "In a world without walls and fences, who needs Windows and Gates?"
