figure out bochs keypress and clock speed and timecounter?

I have used bochs successfully for several years. It is normal to have to 
adjust keyboard_serial_delay and cpu: ips and after a few tries an 
acceptable setting can be found.

But yesterday, I couldn't figure out keyboard_serial_delay on amd64 
1895.61 MhZ running NetBSD -current.

I have tried numerous from 5 (lowest allowed) to 150000. At the boot 
loader I can type fine, but once NetBD comes up (booting i386 NetBSD) my 
keys always repeat way too fast.  For example:  
nnnnnnnneeeeeeeeeetttttttttttbbbbbbbbbbbssssssssssssssddddddddddd

At the boot loader itself, I can type "boot" fine though. This problem is 
after the kernel boots.

I built with --enable-show-ips and am using approximately the ips it 
displays 'cpu: ips=12712908'

dmesg (within the bochs) says my cpu is around 127 MHz.

I want it way faster, but I guess I can live with that.

I also tried many keyboard_paste_delays (from lowest allowed 1000 to 
999999999) but didn't notice any difference.

I also tried many vga_update_interval values but didn't notice difference.

To get my keyboard to work I increase my ips way higher than bochs 
reported to like 'cpu: ips=50000000'. Then my keypresses don't repeat (at 
least not as often). My CPU speed (in dmesg) is still 127 MHz.

(I am guessing that is CPU speed is reported wrong anyways, as I think 
even a 450 MHz system can emulate over 150MHz. Is that something the 
kernel benchmarks/figures out and should be precise? Or is that just what 
the system told the speed is?)

But then I get new problems: initial boot up is very slow. For example, 
the boot loader five second countdown takes almost a minute.

But then when NetBSD kernel actually loads, I get the opposite: time is 
going fast. sleep and date are running about triple time.

Maybe this is related -- part of my dmesg in bochs:

Some of my sysctl's:

kern.clockrate: tick = 10000, tickadj = 40, hz = 100, profhz = 100, stathz 
= 100
kern.monotonic_clock = 200112
kern.hardclock_ticks = 21162
kern.timecounter.choice = clockinterrupt(q=0, f=100 Hz) TSC(q=-100, 
f=50000430 Hz) ACPI-Safe(q=900, f=3579545 Hz) i8254(q=100, f=1193182 Hz) 
dummy(q=-1000000, f=1000000 Hz)
kern.timecounter.hardware = ACPI-Safe
kern.timecounter.timestepwarnings = 0


(I never changed them.)

So what I am looking for:

- system to run at correct clock speed so sleep and date are correct

- keypresses to not repeat

- and maybe over 127MHz

I don't know if this is some bochs configuration or NetBSD tunable or 
both.
