if Tru64 is to continue to be supported on Turbolaser) and fixed
translation of physical addresses by clearing PA<42:35> when the real
uncachable bit (43) is set
arch/alpha/ev5.hh:
Change to support 256 ASNs and seperate VA_SPACE checks for EV5 and EV6
also add support proper translation of uncacheable physical addresses
dev/ide_ctrl.cc:
Fix to work with real address translation
