They show up as CPU: AMD Athlon(tm) Processor (900.04-MHz 686-class CPU) Origin = "AuthenticAMD" Id = 0x642 Stepping = 2 Features=0x183f9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR> AMD Features=0xc0440000<<b18>,AMIE,DSP,3DNow!> real memory = 268369920 (262080K bytes) This means you use the "cpu I686_CPU" option in your kernel. The system it replaced (a P-200) required 277K seconds to do a setiathome work unit. The Thunderbird only uses 17K seconds. A system update of 4-stable using my upworld shell script required 1840u seconds from cvsup to installworld. A P-II 400 requires ~4420u seconds. I don't think the gnu compilers are optimized for the additional pipelines that the Thunderbird has over the Intel Pentium's. I haven't had it running long enough to find out what I can do for optimizations.
