Confirmed here (alas) with an Acer Aspire 3104WLMi running Hardy (fglrx
drivers, madwifi drivers). Initially resuming from suspend to RAM was
quite fast, but after recent Ubuntu updates now "suspending" looks
normally fast (except once, trying to suspend ended in "kernel panic")
but resuming takes *minutes* with the hard disk working like crazy.
During this time the screen is black and backlight off, keyboard not
responding. Meanwhile the machine however pings (thru Wi-Fi) and can be
accessed from remote using SSH...

No change in hardware or whatever between the times when it was fast and
now that it has become dreadfully slow.

Once resumed I notice more than 780 MB of swap used when there was
little swap used before suspending.

In the current situation it takes more time to resume from suspend than
to restart from hibernate or event to cold boot... Which makes
suspending to RAM completely useless...
