Subject: [PATCH] fixed syndicate (removed Y restriction) seperated the
 hardware and the software reset. Everything makes much more sense now.
 software reset: don't touch irq 12 handlers(User Interupt Routine) Hardware
 reset: do  touch irq 12

A software reset is issued if a new videomode is set(now it doesn't destroy the UIR)
