Is it possible to specify the kernel that the hardware for which there are

drivers probing for but I don't have in my PC is absent? Since OBSD has no

suspend to disk/RAM, the bootup speed is critical when working with a laptop

in public transport.
Or are there any other possible ways how to speed up the bootup process?

the majority of devices probe faster than you can blink.  only
i'm not sure what your goal is here.  i can boot and start X in about

30 seconds.  if that's too long, you don't have enough time to get any

work done anyway.

You might want to checkout ports/sysutils/dmassage/.
Obviously, under improper use this might disable all hotpluggable USB stuff.
C.

Ideally, you should plug in all USB gadgets you ever plan to use with

the laptop before running dmassage. If you can't do that, then you

should specifically re-enable them. Be sure to enable things like the

SCSI subsystem if you plan to use a USB mass storage device (pen drive,

external hard drive, CD-/DVD-ROM, floppy drive). I made the mistake of

leaving this out once after compiling a custom kernel, then weeks later

plugged in a pen drive and wondered why I wasn't able to mount the damn

thing. (Note this is exactly why you shouldn't compile a custom kernel

unless you know what you're doing.)

OpenBSD can suspend,
man 8 apm
apm -s for standby or apm -z for suspend state. I don't know if it will work

with your device, but it does work on some

You can use config(8) to disable drivers without building a new

kernel, but you really have to know what you're doing. There's a

tool called dmassage in the ports tree (sysutils/dmassage) which

can help determining unused devices by looking at dmesgs's output.
My experience (I tried it once on a Soekris Net4801) is that doing

this kind of tuning won't gain you much speed at but time but is a

real PITA if you want to plug some new device and have to re-enable

it first to use it.

Automake and autoconf deserve to wither and die, but unfortunately noone

at GNU seems to make much of an effort to euthanasize them.

Look at config(8). There is also an entry in the FAQ:
