Hello, is 915G supported?
alas not, and it never was, AFAICT. i945 is supported and i855 was once.
Is it hard to implement support for Gigabyte 8i915md-g?
It very much depends on your skillset. It's not hard compared to a modern mainboard. However, it could still take some months. Given that there is code for newer and older Intel platforms available, all the information needed to understand what needs to be done for i915 should be public. Finding the exact sequence of bits to toggle could be done with a tool like serialice. Datasheets of that time might also provide rather comprehensive register descriptions.
Beside the northbridge, you'd also need code for the CPU, the south- bridge and likely a super-i/o. Your CPU might be supported, for the southbridge it's roughly the same as for the northbridge, but easier.
