question to those who know x86 irq vectors

Hi,

KDB defines KDB_VECTOR for x86 machines
    #define KDB_VECTOR             0xfb for x86_64 systems,
and #define KDB_VECTOR             0xf9 for x86_32 systems.

In 2.6.27-rc, unfortunately, 0xf9-0xff are all being used. Is it
safe for KDB to use 0xf8? The f0-f7 are used for TLB flush.

Thanks,
 - jay
