I have to agree with Hyp here
nearly 100%. In particular, this part of the FAQ in the lance question:
When the combat rules speak of “two-handed” weapons,
they’re referring to how the weapon is being used. A Medium
character using a Medium longsword in two hands is using a
“two-handed” weapon. The same character using a Medium
lance in one hand while mounted is using a one-handed
weapon.
Completely conflicts with the 3.5 SRD (my emphasis):
Light, One-Handed, and Two-Handed Melee Weapons: This designation is a measure of how much effort it takes to wield a weapon in combat.
It says nothing about how the weapon is being used at the time.
Now, my only minor nitpick is that the 'two-handed' wording, is in fact explicitly in the descriptions of the bastard sword and dwarven waraxe:
A character can use a bastard sword two-handed as a martial weapon.
Thus, taking the literal interpretation of the phrase "two-handed" (which I do) as referring
only to the weapon encumbrance class, when you have MWP (bastard sword) or have a class that includes martial proficiencies, you can wield the bastard sword two-handed--
not one-handed with two hands.
Similarly, if you have EWP (bastard sword) and do not have martial proficiency with the weapon (say a Cleric with only the EWP (bs) feat), you can not wield it two-handed. You can only wield it one-handed--which does include the option of one-handed with two hands--and would never get the +4 disarm bonus for it.
So, at least on this one point--with that condition of having the proficiency--I'd agree with the Sage, although I agree that the implied logic (that those weapons 'default' to two-handed) in the answer of that question is rather suspect. And although I generally agree with Hyp's "bigger is better" rule of thumb, I think there's clear evidence that your training can change that slightly for a few weapons in the core. It all comes back to the straightforward SRD phrase: "how much effort".
