I'm not loading any drivers in my new kernel, I'm just doing pure BIOS disk I/O using Int13 calls (the program I start using kexec I would not actually call a 'kernel', it's just a very tiny piece of software which does some disk I/O and output on the screen).

Attached you find the output of lspci -v

Best regards
Christian
