Madwifi versus Ath5k

Ikke at jeg har planer om at fylde på dette forum i større stil, men:
Jeg har en IBM Thinkpad T40p. Det er på ingen måde en ny maskine, men specifikationerne dækker mine behov til en computer, og formatet er fint.
Der er så én ting, der fortjener beklagelse (lige bortset fra, at min søn på snart 3 år har revet 3 af tasterne af, men jeg kan jo ikke bebrejde andre for hans dårlige opdragelse (end min kone)): Maskinen har et indbygget wireless-kort - hvilket i øvrigt er forskellen på en T40 og en T40p - og dette foregiver at være et kort med et velkendt Atheros-chipsæt.
Det er det imidlertid ikke, eller også er det, men så har IBM tilsat en portion problematik til den cocktail, for: Der blev lavet en lukket Linux-driver ved navn Madwifi. Denne fungerede et godt stykke tid. Så besluttede man imidlertid at lægge en åben driver ind i Linux-kernen - benævnt Ath5k, fordi det var Atheros 5xxx-chipsene, den understøtter.
Den klodser bare i det, når man skal bruge dette specifikke wifi-kort og kryptering. Og de senere varianter af Linuxkernen kan ikke umiddelbart anvende Madwifi.
Så resultatet er, at jeg har en computer med indbygget wireless, som reelt kun kan bruges med et åbent netværk. Derudover skal jeg bruge et eksternt kort eller, som jeg gør i øjeblikket, mobilbredbånd.

I princippet skulle det kunne lade sig gøre at rive kortet ud af karosseriet og erstatte det med et andet kort, som maskinen genkender som IBM-certificeret (yep, det checker maskinen for) - så hvis jeg kan få et af de andre, der også blev brugt i T4x-serien, og som er Intel 2200-baserede, så kunne det lade sig gøre. Men at det kræver maskinkirurgi at løse et problem, der er dobbelt-dækket ind med drivere, det virker fjollet.

Jeg kan ikke se, hvilket chipset, der er på dette her :crossfingers: :
Men jeg har i mangel af nærmere, handlet med pchub helt uden vrøvl. De var flinke til at svare på spørgsmål også.

Det ser gangbart nok ud.

Ha! Ja, det kunne være en idé. Reservedele kan vi altid bruge.
