New Revision: 28986
ViewCVS: http://svn.berlios.de/viewcvs/haiku?rev=28986&view=rev

Modified:
   haiku/trunk/src/system/kernel/arch/x86/apm.cpp
Log:
Comment out problematic inline asm statement for GCC 4. The direct reference
to sAPMBiosEntry generates undefined symbols and I'm not in a condition to fix
this right now. Added a TODO.
