My K6 works fine.  Which cache did you turn off in the BIOS the L1 or the L2?
If the L2 then it sounds like your L2 cache might be messed up, which you
may be able to fix with new cache memory or a new motherboard, depending on how
it is messed up.

CPU: AMD-K6(tm) 3D processor (300.68-MHz 586-class CPU)
  Origin = "AuthenticAMD"  Id = 0x580  Stepping = 0
  Features=0x8001bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,MMX>
  AMD Features=0x80000800<SYSCALL,3DNow!>
real memory  = 67108864 (65536K bytes)
avail memory = 62214144 (60756K bytes)
