o.k. I have reset the kernel to 2.6.36 and ran the test program in
init 3(since radeon is crapped out with that kernel). anyways
with 2.6.36 I can see the cursor on the bottom left blinking throught 
the whole tests telling me there is no pause(all timeouts given, give no 
pause).
with the current in init 3 I see the cursor pause for 2/3 seconds.

I will start a bisct on this, but need some help on how to proceed 
properly i.g. I get an error with gcc building:

   LD      init/built-in.o
   VDSO    arch/x86/vdso/vdso.so.dbg
gcc: error: elf_x86_64: No such file or directory
   VDSO    arch/x86/vdso/vdso32-int80.so.dbg
gcc: error: elf_i386: No such file or directory
   VDSO    arch/x86/vdso/vdso32-syscall.so.dbg
gcc: error: elf_i386: No such file or directory
   VDSO    arch/x86/vdso/vdso32-sysenter.so.dbg
gcc: error: elf_i386: No such file or directory
   CC      kernel/trace/trace.o

its easily fixable, but not sure its a good idea due to bisect going 
through commits(afraid I might go astray with the bisect if I add any 
patches).
