Kernel not recognizing your hardware? Problems with power management or PCMCIA? What hardware is compatible with Gentoo? See here. (Only for kernels supported by Gentoo.)
That depends on what you'd like to monitor. There are lots of choices, obvious ones are gkrellm and SuperKaramba. They mostly depend on lm_sensors. But you could be searching for some other kind of functionality.
I have a SuperKaramba theme running that shows my current CPU speed, CPU temperature, motherboard temperature, CPU usage, memory usage etc. Other options (like voltages) can be added.
You can do this with sys-apps/lm_sensors (no GUI) and then there are some applications that access the information provided by lm_sensors (ksensors, gkrellm, etc...).
I am using adesklets. The SystemMonitor desklet shows cpuload, memused, acpi ( in my case i2c ) temperatures,
free space on mountpoints, netload, ....
You will have to edit some skripts to suit it to your needs, but it looks great.
If you already use gnome, you can have about the same features by using gDesklets, for KDE there is karamba.
Not to forget torsmo, which is less eyecandy but can show nearly anything on your desktop...
For xfce4 there are some nice plugins for the starterbar...
So it depends on which DE you use...

lm_sensors is obviously a must...
as for monitoring apps, I ran across something called conky the other day. It seems to work quite nicely. Runs in a small transparent terminal. http://conky.sourceforge.net/
I won't compare hot-babe to lm_sensors but you should try this one as well... it is funy... You'll love your very slow machines
Just to make sure young fragile kid don't get lost somewhere looking for hot babes... here is the link : http://dindinx.net/hotbabe/index.php
