Sorry, the workaround I stumbled upon was just a coincidence... For
some, probably random reason, the delay was reduced to ~5 seconds for a
number of boots. However, I have now found a REAL workaround... =)

With splash disabled, I looked carefully at the boot text and found that
the freezes were followed by "clocksource tsc unstable", after which the
system switched source to "hpet" and continued booting.

I added the boot parameter "clocksource=hpet" in grub, and now
everything works like a charm.

I guess my CPU is relevant here, all I can tell you about it is that it
is a Celeron M. As far as I know, that is a single-core cpu without
frequency scaling support.

I'm kind of happy now as the problem is gone, and I hope you can use
this info to fix the issue in a future update/release. I am sure many
others are having this problem: most of them probably without knowing
it... Even with the one minute delay, my particular laptop still boots a
lot faster than any computer with Vista I have ever tried.

My laptop is an HP 530 (P/N FH523AA#AK8). It seems to be a pretty common
"Linux PC", as it is VERY cheap, all its hardware works with Ubuntu and
many stores are selling it without a Windows license.

In all essence, my machine is right out of the box:
- BIOS settings are unchanged from default
- Problem persisted with no external accessories connected to the computer
- I have not changed anything hardware wise except adding a memory module
- Both Windows XP and Vista works as well as they ever do on the machine, 
ruling out hardware error
- The problem existed even when booting the system from the Live CD, ruling out 
any misconfiguration from my part

If there is any more info you need from me, I'll be happy to supply it!
