after sync, 2 different Gmail contact groups are merged in 1 on iPad - how to separate?

iPad2, ios 5.0.1 (9A405).

In my Gmail account I have 2 groups of contacts: "group a" and "group b".

However, after I sync my iPad contacts with Gmail, contacts in both "group a" and "group b" are are lumped together in "All Contacts" on the iPad.

How can I get them separated?

ALL Contacts .. does exactly that. Shows ALL Contacts in your Address Book.
In the Contacts App you can usually see the GROUPS button at the top of the screen when in List view .. if you click on this it will show you all the different GROUPS for your Contacts.  As long as you have different Categories/Groups in your Google Calendars you should be able to separate them using these GROUPS.  By default Contacts will merge ALL Gmail, Apple Address Book and other contacts when you select the "ALL Contacts" grouping.

I do not see a Groups button.

Please see the attached .pdf which has all applicable screenshots.

It looks like the Sync Support for Google Contacts is more limited than the Apple Address Book.. see the following article

You can choose to sync the All Contacts or My Contacts

You might want to look at Google iPhone/iPad sync app instead as it may have better support
