f1a227f182 XGA changes of the day (July 5th, 2025) 
1. Remove hackish ISA XGA add-on support (from now on, use the INMOS XGA card for ISA XGA support).
2. Correct timings when dispontime is on.
3. Add proper vga256 support on ISA XGA for NT 3.5x+ as well disable LFB support when asked (mainly when the aperture is on or when not extended mode) while keeping everything else happy.

5fbcbde4ba More fixes to the mode switching of the ATI/IBM 8514/A compatibles (June 28th, 2025) 
The mode switching phase now takes account of the display enable/reset bits of port 0x22e8 (bits 5-6). Fixes Solaris mode switching and keeps everything else happy (I hope).
