Blackpool have signed Derby striker Kwame Thomas on a six-month loan.
The France midfielder was the subject of a bid from Arsenal on the eve of the campaign and, while that was rejected out of hand, manager Alan Pardew kept him out of the side for the first two matches of the season.
Reports quickly followed that Cabaye's head had been turned by the Gunners and he was agitating to push the transfer through.
But the transfer window shut without further developments and Cabaye returned to the starting XI for Saturday's 2-1 win at Aston Villa, having come on as a substitute the previous weekend against Fulham.
He was warmly applauded by the Magpies' travelling fans when he was substituted late on, but he accepts he has some making up still to do.
"(The fans' response) was very nice to hear. If the fans were - or still are - mad at me for what happened then I understand and I apologise to them," he told www.nufc.co.uk.
"I want to come back from what has happened. I was happy and I am still happy.
"I just want to try and score goals and play well.
"It was very, very good to be back in the team; a really nice feeling."
While Newcastle may be buoyed by Cabaye's words, he appeared to suggest his new-found commitment extended only to the end of the current campaign.
He added: "For Newcastle fans, football is their life and I want to say that I am going to give everything - as I have from my first day here - from today until the end of the season.
"It is important I do that because Newcastle is my club and there is a World Cup at the end of the season, which I want to play in.
"It is very important to be right in my head and I am."
The 27-year-old Frenchman, who has been an influential performer since his arrival from Lille, admitted recent weeks had constituted a "bad moment" for him but is not suffering a major hangover from it.
"I'm okay. This is football," he said.
"You do not have a career without bad moments. I have moved on and now in my head I just want to work really hard, to get back in the team every week and to help the team - that is the most important thing for me.
"I want to forget what happened during the summer, I want to put it behind me and give everything for Newcastle every day, for the club and for my team-mates."
