Appying these 2 patches to 2.6.35-rc5 didn't help, the machine is stalling
as usual and several key presses are required to get it to boot.

Did it, and now it boots fine without any delay/stalling.
Did also try stock/vanilla 2.6.35-rc5 with "nolapic_timer hpet=verbose",
and it does boot fine, too.

Attached are three files,

dmesg-01 = output of 2.6.35-rc5 + the two patches
dmesg-02 = output of 2.6.35-rc5 + the two patches + "nolapic_timer
 hpet=verbose"
dmesg-03 = vanilla 2.6.35-rc5 + "nolapic_timer hpet=verbose"

Thanks,
Heinz.
