linuxbios can't identify celeron 850MHz

[zhu shi song]

Hi, everyone,
  I met one problem, linuxbios can't identify celeron
850Mhz.
i'm using linux-kernel 2.4.18, cvs-freebios,
winfast6300.
when using linuxbios boot, linux can't identify
celeron
850MHz, it shows the cpu is at 560MHz.
when using normal bios boot, linux can identify
celeron
850MHz, it shows the cpu is at 850MHz.
what's the problem, please help me.

thanks
          zhu
