To answer my own question: It looks I want geiser-mode-switch-to-repl-and-enter. Great. That works close to what I'd hoped.
Unfortunately I'm encountering a problem where sometimes Geiser gets into a state such that switching away from the "* Racket REPL *" buffer (with e.g. C-x o) will create a buffer named "*spurious*" with contents like this: ----- stdin::332: read: unexpected `)' c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:57:15: ((current-read-interaction) (object-name in) in) c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:56:2: (let-values (((form) ((current-read-interaction) (object-name in) in))) (let-values (((arg) (datum->syntax (....) ....))) (let-values (((....) ....)) (let-values ....)))) === context === c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:53:0 C:\Program Files (x86)\Racket\collects\racket\private\misc.rkt:74:7 rac...@dns.rkt> stdin::333: read: unexpected `)' c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:57:15: ((current-read-interaction) (object-name in) in) c:\users\greg\site\geiser\scheme\racket\geiser\user.rkt:56:2: (let-values (((form) ((current-read-interaction) (object-name in) in))) (let-values (((arg) (datum->syntax (....) ....)))

For instance *spurious*<2>, *spurious*<3> and so on.
