Would I ever have a chance to boot it 64bits?

Here are some additional strage stuff:
[snip]
CPU(s): 1 x PA8000 (PCX-U) at 180.000000 MHz
Whole cache flush 378186 cycles, flushing 274443696 bytes 107618208 cycle=
s
Setting cache flush threshold to 0xeb780 (1 CPUs online)
[snip]
LASI 82596 driver - Revision: 1.30
Found i82596 at 0xffffffffffd07000, IRQ 17
eth0: 82596 at 0xffffffffffd07000, 00 00 00 00 08 00 IRQ 17.
[snip]

while the 32bit kernel said:
[snip]
Setting cache flush threshold to 20 (1 CPUs online)
[snip]
LASI 82596 driver - Revision: 1.30
Found i82596 at 0xffd07000, IRQ 17javascript:OnPhoenixSend();
eth0: 82596 at 0xffd07000, 08 00 09 D2 89 15 IRQ 17.
[snip]

Questions are:
    o could it be that 'cache flush threshold' value was the reason why t=
he
system became so slow?
       (couldn't it be why ncr doesn't start correctly?
        s=3D2 sec in top actualy means about 30sec between 2 changes in d=
isplay
:-( )
    o Is nic 82596 is not 64bit ready? (apparently didn't report the righ=
t
MAC Address?)

Thanks in advance for help,
    Joel
