1. Made the 4 color mode (67h) work properly now, including its 4 schemes on all ATI cards that support said mode.
2. Shadow set now has a true purpose for 8514/A compatibility on ATI Mach8/32.
3. Non-ATI 8514/A used to not work before because of the dev->local variable was not being set to 0 in the ibm8514_init() function, now it's fixed.
