Olá!

De posse destas informações, você poderia:

1 - atualizar o seu kernel. O lenny possui uma versão mais nova do que a que
você está usando.

2 - Voltar a usar o kernel e sistema i386 ao invés do amd64. Especialmente se
o hardware era o mesmo que você tinha instalado o debian antes de passar para
a versão mais atual. Hardware muito  "novo"  não costuma se dar muito bem com
kernel antigo. Pense nisso.

3 - Procurar uma solução atual para o seu problema antigo (considerar que
hostap é muito mais flexivel e fácil de se implementar que madwifi, o qual se
tornou obsoleto. Debian lenny é versão estável obsoleta. O site do madwifi não
tem uma update desde... mais de 5 anos atrás. Projeto abandonado).

4 - considerar que o seu hardware pode ter  chegado ao final da vida util dele,
se tiver mais que 3 anos. Experimente colocar esta placa wifi em outro
computador, e ver se  o problema persiste. E colocar uma outra placa wifi no
seu computador, para ver se o problema talvez seja com ele.

Abraços
Tux
