I have this setup:

ECS K7S5A
AMD Athlon 2200+ (thoroughbred core)
IDE/ATAPI DVD-RW/CDRW & DVD ROM Drives (2 drives)
maxtor 7200 rpm uata133 hard drive (motherboard's controller is udma100)
sb live (emu10k1)
nvidia geforce 3

A. What is Local APIC support?
B. What is IO-APIC support?
C. What is Unsynced TSC Support?
D. Do I need to compile any of these in my kernel?
E. If I don't, who does?

PS.:
With my current kernel cat /var/log/dmesg | grep APIC reveals:
ACPI: RSDP (v000 AMI ) @ 0x000fa310
ACPI: RSDT (v001 AMIINT SiS735XX 0x00001000 MSFT 0x0100000b) @ 0x1fff0000
