cpu, and debian install questions

Hello all,

I just got a box here, on which I'm running grml64 2010.4 off
the cd so I can explore around, and I have a couple of questions which
I hope someone could provide meaningful answers to:

1. When I look at dmesg, I see:

[    0.000000] Detected 2188.958 MHz processor.
[    0.003345] Calibrating delay loop (skipped), value calculated
using timer frequency.. 4379.32 BogoMIPS (lpj=7296526)

However, when I look at /proc/cpuinfo, I see this:

processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 39
model name      : AMP Athlon(tm) 64 Processor 3700+
stepping        : 1
cpu MHz         : 1000.000
cache size      : 1024 KB
fpu             : yes
fpu_exception   : yes
cpuid level     : 1
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext
fxsr_opt lm 3dnowext 3dnow up rep_good pni lahf_lm
bogomips        : 1990.87
TLB size        : 1024 4K pages
clflush size    : 64
cache_alignment : 64
address sizes   : 40 bits physical, 48 bits virtual
power management: ts fid vid ttp tm stc
Why is cpuinfo showing the cpu is 1GHz, when in fact it is a 2.2GHz
processor? Something to do with power management? I assume that linux
will still take full advantage of the processor, am I correct in
assuming that?

My second question is what is the easiest way to install debian Lenny
64-bit on this system without a serial port? I do have a usb to serial
converter here, but that won't work with speakup as of now
obviously. I know I can mess around with debootstrap under grml, but
is there an easier way?

Thanks in advance for any help.
