[PATCH 2/21] i386 Always relax segments
APM BIOSes have many bugs regarding proper representation of the appropriate segment limits for calling the BIOS. By default, APM_RELAX_SEGMENTS is always turned on to support running the APM BIOS on these buggy machines. Keeping 64k limits poses very little danger to the kernel, because the pages where the APM BIOS is located will always be in low physical memory BIOS areas, which should already be marked reserved, and only buggy BIO...
