After that I have enabled the whole video RAM section A0000 - BFFFF as read/write/cache 0x07070067:
I would assume that the video ram must not be cacheable! It doesn't get written to very much by the bios anyways (except probably the int10 calls)
I have also the long delay by vga initializing, but after upcoming there are only unreadable characters on the screen.
Yes, cacheable video memory does not work. When the CPU caches things there the VGA controller only sees half of what it is supposed to see.
