the one year multi entry was NEVER listed on their website
The thai consulate in Savannakhet issues year-long multi-entry Non-O visas based on marriage to a thai ONLY if you have 400K baht in a thai bank account seasoned for 2 months before you go apply for the visa,
Anything else and you get a single entry Non-O for 90 days.
That's how it is, it's not listed anywhere, but after checking with two companies who do nothing but lug people to that consulate for visas that is the policy they are enforcing up there now.
Update your thai bank book the day before you cross the border, there's no way to update it in Lao.
