[OpenBIOS] r331 - cpu/x86/pc/olpc

[svn at openbios.org]

Author: wmb
Date: 2007-04-28 00:18:48 +0200 (Sat, 28 Apr 2007)
New Revision: 331

Modified:
   cpu/x86/pc/olpc/devices.fth
   cpu/x86/pc/olpc/fw.bth
Log:
OLPC - the clock frequency for the LX version is higher, so us-factor,
ms-factor, and the CPU node clock-frequency property must be version-specific.
