A follow up of the U205 situation.
It looks like Tejun Heo has found the problem and posted a patch that
makes my machine suspend to RAM very fast using the latest official
kernel.
You can read more about it here:

Hello,
I have found the problematic module that don't allow suspend to ram to
work in the Toshiba U205 S5067 laptop: it is the sata driver. This
laptop has as an Intel ICH7 Family SATA controller that uses the libsata
+ ata_piix module.
I had a hint that the SATA module could be the problem afte

OK,
I have been able to make the current Ubuntu kernel (2.6.20 patched by
Ubuntu) play nice with suspend to ram: I have recompiled the kernel
using the kernel.config from LDFK (found in the iniramfs in their source
code tree) file as configuration file. Just type "make menuconfig", load

I have also tried the LFDk CD and my machine also suspended right away.
I have been trying to hunt this bug down, adding many printk to my
kernel to see where the time is being spend.
Up to now I can see that the system I get the following:
enter_state in kernel/power/main.c is called that calls
