Subject: is kernel slower at loading for some hardware ?

Hi,

during boot up, I am trying to find where the kernel takes more time
to do actions (is slower ?).
I looked at dmesg and found some places where it takes more time, but
not sure if this is normal :

[    0.070964] smpboot: CPU0: AMD Athlon(tm) 7750 Dual-Core Processor

Not sure if it is normal or not...maybe it's just normal behavior or
cannot get any faster...

Thanks for reading.
Cheers
